Praise be to Allaah.
There is no doubt that the Isra’ and Mi’raaj (the Prophet’s Night Journey and Ascent into heaven) are two great signs of Allaah which point to the truthfulness of the His Messenger Muhammad (peace and blessings of Allaah be upon him), and the greatness of his status before Allaah. They are also signs of the great power of Allaah, and of His exalted position above His creation. Allaah says (interpretation of the meaning):
“Glorified (and Exalted) be He (Allaah) [above all that (evil) they associate with Him]
Who took His slave (Muhammad) for a journey by night from Al‑Masjid Al‑Haraam (at Makkah) to Al‑Masjid Al‑Aqsa (in Jerusalem), the neighbourhood whereof We have blessed, in order that We might show him (Muhammad) of Our Ayaat (proofs, evidences, lessons, signs, etc.). Verily, He is the All‑Hearer, the All‑Seer”
There are mutawaatir reports from the Messenger of Allaah (peace and blessings of Allaah be upon him) that he was taken up into the heavens, and their gates were opened for him, until he passed beyond the seventh heaven, where his Lord spoke to him as He willed, and enjoined the five daily prayers upon him. At first Allaah, may He be exalted, enjoined fifty prayers, but our Prophet Muhammad (peace and blessings of Allaah be upon him) kept going back and asking Him to reduce it, until He made them five, so they are five obligatory prayers but fifty in reward, because each good deed is rewarded tenfold. To Allaah be praise and thanks for all His blessings.
With regard to this night on which the Isra’ and Mi’raaj took place, there is nothing in the saheeh ahaadeeth to indicate that it is in Rajab or in any other month. Everything that has been narrated concerning a specific date for these events cannot be proven to have come from the Prophet (peace and blessings of Allaah be upon him) according to the scholars of hadeeth. Allaah has wise reasons for causing the people to forget it. Even if the date were proven, it would not be permissible for the Muslims to single it out for particular acts of worship, and it is not permissible for them to celebrate it, because the Prophet (peace and blessings of Allaah be upon him) and his companions (may Allaah be pleased with them) did not celebrate it and they did not single it out in any way. If celebrating it was something that is prescribed in Islam, the Messenger would have told his ummah about that, either in word or in deed. If any such thing had happened, it would have been well known, and his companions would have transmitted the information to us. They narrated from their Prophet (peace and blessings of Allaah be upon him) everything that his ummah needs to know, and they did not neglect any aspect of the religion, rather they were the first ones to do anything good. If celebrating this night had been prescribed in Islam, they would have been the first people to do so. The Prophet (peace and blessings of Allaah be upon him) was the most sincere of people, and he conveyed the message to the people in full, and he fulfilled the trust. If venerating and celebrating this night were part of the religion of Allaah, then the Prophet (peace and blessings of Allaah be upon him) would have done that and would not have concealed it. Since no such thing happened, it is known that celebrating it and venerating it is not part of Islam at all. Allaah has perfected this ummah’s religion for it and has completed His favour upon them, and He condemns those who introduce things into the religion which Allaah has not ordained. Allaah says in His holy Book, in Soorat al-Maa’idah (interpretation of the meaning):
“This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion”
And Allaah says in Soorat al-Shoora (interpretation of the meaning):
“Or have they partners with Allaah (false gods) who have instituted for them a religion which Allaah has not ordained?”
