This concept is not detailed explicitly in the Quran but in many of the interpretations and the Ahadith.
Of course, Muhammad, as usual, PLAGIARISED this concept from the Jews and Christians since it did not exist in the simple religion of the pagan Arabs.
2: 177It is not righteousness that ye turn your faces toward East or West; but it is righteousness to believe in Allah and the Last Day and the Angels and the Book and the Messengers; to spend of your substance out of love for Him for your kin for orphans for the needy for the wayfarer for those who ask and for the ransom of slaves; to be steadfast in prayer and practice regular charity; to fulfil the contracts which ye have made; and to be firm and patient in pain (or suffering) and adversity and throughout all periods of panic. Such are the people of truth the Allah-fearing……. 232When ye divorce women and they fulfil the term of their (`Iddat) do not prevent them from marrying their (former) husbands if they mutually agree on equitable terms. This instruction is for all amongst you who believe in Allah and the Last Day. That is (the course making for) most virtue and purity amongst you and Allah knows and ye know not
9: 29Fight those who believe not in Allah nor theLast Day nor hold that forbidden which hath been forbidden by Allah and His apostle nor acknowledge the religion of truth (even if they are) of the People of the Book until they pay the Jizya with willing submission and feel themselves subdued.
Tabari 1:181 " The Prophet said 'I was sent immediately before the coming of the Day of Doom. I preceded it like this one preceding that one' -referring to his index and middle finger" 182 "he said 'Allah will not make this nation [of Islam] incapable of lasting half a day -a day being a thousand years- …Consequently, based upon the Prophet's authority,, what remained of time was half a day that had elapsed to the Prophet's statement corresponds to 6500 years"
*** Based on Muhammad's prophecy, Dooms Day should have occurred 500 years after this 'revelation' which occured about 610 AD.
Well, as we all know, the year 1110 had already passed and we are in the year 2007 AD without the prophecy of the infallible 'Prophet' having come true.
Muhammad's alleged prophecies may be counted on one hand none of which ever came true***
Sunan of Abu-DawoodHadith 2153Narrated byRuwayfi' ibn Thabit al-Ansari
Should I tell you what I heard the Apostle of Allah (peace be upon him) say on the day of Hunayn: It is not lawful for a man who believes in Allah and the last day to water what another has sown with his water (meaning intercourse with women who are pregnant); it is not lawful for a man who believes in Allah and the Last Day to have intercourse with a captive woman till she is free from a menstrual course; and it is not lawful for a man who believes in Allah and the Last Day to sell spoil till it is divided.
Sunan of Abu-DawoodHadith 2702Narrated byRuwayfi' ibn Thabit al-Ansari
The Prophet (peace be upon him) said: He who believes in Allah and the Last Day must not ride on packhorse belonging to the booty of the Muslims and put it back when he has emaciated it; and he who believes in Allah and the Last Day must not wear a garment belonging to the booty of the Muslims and put it back when he made it threadbare.
Al-Tirmidhi HadithHadith 4477Narrated byJabir ibn Abdullah
The Prophet (peace be upon him) said, "He who believes in Allah and the last day must not enter a bath without a lower garment. He who believes in Allah and the last day must not bring his spouse into a bath. And he who believes in Allah and the last day must not sit at a cloth where wine is being circulated."
Tirmidhi and Nasa'i transmitted it.
Sahih Muslim HadithHadith 1862Narrated byAbuHurayrah and Hudhayfah
The Messenger of Allah (peace be upon him) said: It was Friday from which Allah diverted those who were before us. For the Jews (the day set aside for prayer) was Sabt (Saturday), and for the Christians it was Sunday. And Allah turned towards us and guided us to Friday (as the day of prayer) for us. In fact, He (Allah) made Friday, Saturday and Sunday (as days of prayer). In this order would they (Jews and Christians) come after us on the Day of Resurrection. We are the last of (the Ummah) among the people in this world and the first among the created to be judged on the Day of Resurrection. In one narration it is: "to be judged among them".
*** As usual with Muhammad, he got the concept of the Sabbath/ Saturday as aday of prayers WRONG.
In FACT, God ordained upon the ISRAELITES to make SABBATH/ Saturday a day of cessation of work; a day for introspection and a day to enjoy God's creation, BUT NOT a day of PRAYERS ***
Sahih Al-Bukhari HadithHadith 2.194Narrated byAbu Huraira
The Prophet (p.b.u.h) said, "It is not permissible for a woman who believes in Allah and the Last Day to travel for one day and night except with a Mahram."
Sahih Al-Bukhari HadithHadith 2.371Narrated byZainab bint Abi Salama
I went to Um Habiba, the wife of Prophet, who said, "I heard the Prophet saying, 'It is not legal for a woman who believes in Allah and the Last Day to mourn for any dead person for more than three days except for her husband, (for whom she should mourn) for four months and ten days'." Later I went to Zainab bint Jahsh when her brother died; she asked for some scent, and after using it she said, "I am not in need of scent but I heard Allah's Apostle saying, 'It is not legal for a woman who believes in Allah and the Last Day to mourn for more than three days for any dead person except her husband, (for whom she should mourn) for four months and ten days.' "
Sahih Al-Bukhari HadithHadith 5.589Narrated byAbu Shuraih
Al-Adawi that he said to 'Amr bin Said while the latter was sending troops in batches to Mecca, "O chief! Allow me to tell you a Statement which Allah's Apostle said on the second day of the Conquest of Mecca. My two ears heard it and my heart remembered it and my two eyes saw him when he said it. He (i.e. the Prophet) praised Allah and then said, 'Mecca has been made a sanctuary by Allah and not by the people, so it is not lawful for a person, who believes in Allah and the Last Day to shed blood in it, or to cut its trees and if someone asks the permission to fight in Mecca because Allah's Apostle was allowed to fight in it, say to him; Allah permitted His Apostle and did not allow you, and even he (i.e. the Apostle) was allowed for a short period of the day, and today its (Mecca's) sanctity has become the same as it was before (of old) so those who are present should inform those who are absent (this Hadith)." Then Abu Shuraih, was asked, "What did 'Amr say to you?" Abu Shuraih said, "He said, 'I knew that better than you, O Abu Shuraih! The Haram (i.e. Mecca) does not give refuge to a sinner or a fleeing murderer or a person running away after causing destruction.' "
*** The above Hadith is a manifest lie since these PROHIBITIONS were in the tradition of the Pagan Arabs long BEFOREMuhammad and his Quran.
Muhammad, as usual, 'ISLAMIZED' and subsumedwhat were PAGAN TRADITIONS ***
