I remarked to 'Umar al-Khattab: Have you seen the shortening of the prayer by the people today while Allah has said: "If you fear that those who are infidels may afflict you", whereas those days are gone now? He replied: I have wondered about the same matter for which you wondered. So I mentioned this to the Messenger of Allah ﷺ. He said: It is an act of charity which Allah has done to you, so accept his charity.
قُلْتُ لِعُمَرَ بْنِ الْخَطَّابِ أَرَأَيْتَ إِقْصَارَ النَّاسِ الصَّلاَةَ وَإِنَّمَا قَالَ تَعَالَى { إِنْ خِفْتُمْ أَنْ يَفْتِنَكُمُ الَّذِينَ كَفَرُوا } فَقَدْ ذَهَبَ ذَلِكَ الْيَوْمُ فَقَالَ عَجِبْتُ مِمَّا عَجِبْتَ مِنْهُ فَذَكَرْتُ ذَلِكَ لِرَسُولِ اللَّهِ ﷺ فَقَالَ صَدَقَةٌ تَصَدَّقَ اللَّهُ بِهَا عَلَيْكُمْ فَاقْبَلُوا صَدَقَتَهُ
