Narrated Ya'la bin Umayyah: "I said to 'Umar [bin Al-Khattab]: 'Allah said: That you shorten the Salat if you fear and the people are safe (4:101).' So 'Umar said: 'I wondered about that just as you have wondered. So I mentioned that to the Messenger of Allah (ﷺ), and he said: "It is charity which Allah has given to you, so accept His charity."

حَدَّثَنَا عَبْدُ بْنُ حُمَيْدٍ، أَخْبَرَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، قَالَ سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ عَبْدِ اللَّهِ بْنِ أَبِي عَمَّارٍ، يُحَدِّثُ عَنْ عَبْدِ اللَّهِ بْنِ بَابَاهُ، عَنْ يَعْلَى بْنِ أُمَيَّةَ، قَالَ قُلْتُ لِعُمَرَ بْنِ الْخَطَّابِ إِنَّمَا قَالَ اللَّهُ ‏:‏ ‏(‏ أَنْ تَقْصُرُوا مِنَ الصَّلاَةِ إِنْ خِفْتُمْ أَنْ يَفْتِنَكُمُ الَّذِينَ كَفَرُوا ‏)‏ وَقَدْ أَمِنَ النَّاسُ ‏.‏ فَقَالَ عُمَرُ عَجِبْتُ مِمَّا عَجِبْتَ مِنْهُ فَذَكَرْتُ ذَلِكَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ ‏"‏ صَدَقَةٌ تَصَدَّقَ اللَّهُ بِهَا عَلَيْكُمْ فَاقْبَلُوا صَدَقَتَهُ ‏"‏ ‏.‏ قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ ‏.‏
