Sunan Abi Dawud, Hadith 4663 ⓘ
Ibn ‘Abbas said: when the Prophet (May peace be upon him) turned towards the Ka’bah (in prayer), the people asked : Messenger of Allah (May peace be upon him)! what will happen with those who died while they prayed with their faces towards Jerusalem ? Allah the Exalted, then revealed : “And never would Allah make your faith of no effect.”
حَدَّثَنَا مُحَمَّدُ بْنُ سُلَيْمَانَ الأَنْبَارِيُّ، وَعُثْمَانُ بْنُ أَبِي شَيْبَةَ، - الْمَعْنَى - قَالاَ حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، عَنْ سِمَاكٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ لَمَّا تَوَجَّهَ النَّبِيُّ صلى الله عليه وسلم إِلَى الْكَعْبَةِ قَالُوا يَا رَسُولَ اللَّهِ فَكَيْفَ الَّذِينَ مَاتُوا وَهُمْ يُصَلُّونَ إِلَى بَيْتِ الْمَقْدِسِ فَأَنْزَلَ اللَّهُ تَعَالَى { وَمَا كَانَ اللَّهُ لِيُضِيعَ إِيمَانَكُمْ } .
