حَدَّثَنَا يَحْيَى عَنِ ابْنِ جُرَيْجٍ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ بْنِ أَبِي عَمَّارٍ عَنْ عَبْدِ اللَّهِ بْنِ بَابَيْهِ عَنْ يَعْلَى بْنِ أُمَيَّةَ قَالَ قُلْتُ لِعُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ إِقْصَارُ النَّاسِ الصَّلَاةَ الْيَوْمَ وَإِنَّمَا قَالَ اللَّهُ عَزَّ وَجَلَّ إِنْ خِفْتُمْ أَنْ يَفْتِنَكُمْ الَّذِينَ كَفَرُوا فَقَدْ ذَهَبَ ذَاكَ الْيَوْمَ فَقَالَ عَجِبْتُ مِمَّا عَجِبْتَ مِنْهُ فَذَكَرْتُ ذَلِكَ لِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ صَدَقَةٌ تَصَدَّقَ اللَّهُ بِهَا عَلَيْكُمْ فَاقْبَلُوا صَدَقَتَهُ
مسند امام احمد بن حنبل · Hadith 244
It was narrated that Ya'Ja bin Umayyah said: I said to 'Umar bin al-Khattab: People are shortening the prayer today, and Allah says: "If you fear that the disbelievers may put you in trial (attack you)" [an-Nisa' 4:101 ]. But that time [i.e., time of fear] has gone. He said: I wondered the same thing as you are wondering, and I asked the Messenger of Allah (PBUH) about that. He said: "It is a charity that Allah has bestowed upon you, so accept His charity."
