حَدَّثَنَا خَلَفٌ حَدَّثَنَا إِسْرَائِيلُ عَنْ سِمَاك
ٍ عَنْ عِكْرِمَةَ عَنِ ابْنِ عَبَّاسٍ قَالَ لَمَّا حُوِّلَتْ الْقِبْلَةُ قِيلَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ الَّذِينَ مَاتُوا وَهُمْ يُصَلُّونَ إِلَى بَيْتِ الْمَقْدِسِ فَأَنْزَلَ اللَّهُ { وَمَا كَانَ اللَّهُ لِيُضِيعَ إِيمَانَكُمْ }

English Translation
Khalaf narrated to us, Isra'il narrated to us, from Simak, from 'Ikrimah, from Ibn 'Abbas (رضي الله عنهما) who said: When the qiblah was changed, it was said: 'O Messenger of Allah, what about those who died while they were praying toward Bayt al-Maqdis (Jerusalem)?' So Allah عز وجل revealed: 'And Allah would never let your faith go to waste' [al-Baqarah 2:143] — meaning your prayers toward Jerusalem.
