Umar ibn al-Khattab reported: The Prophet, peace and blessings be upon him, dispatched a company to Najd and they acquired many spoils and rushed back. A man who did not go with them said, “We have not seen a company return more swiftly and with better spoils than this one!” The Prophet said, “Shall I not tell you about a people with better spoils and a swifter return? People who attend the dawn prayer, then sit remembering Allah until the sun rises. These have a swifter return and better spoils.”

عَنْ عُمَرَ بْنِ الخَطَّابِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَعَثَ بَعْثًا قِبَلَ نَجْدٍ فَغَنِمُوا غَنَائِمَ كَثِيرَةً وَأَسْرَعُوا الرَّجْعَةَ فَقَالَ رَجَلٌ مِمَّنْ لَمْ يَخْرُجْ مَا رَأَيْنَا بَعْثًا أَسْرَعَ رَجْعَةً وَلاَ أَفْضَلَ غَنِيمَةً مِنْ هَذَا البَعْثِ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَلاَ أَدُلُّكُمْ عَلَى قَوْمٍ أَفْضَلُ غَنِيمَةً وَأَسْرَعُ رَجْعَةً قَوْمٌ شَهِدُوا صَلاَةَ الصُّبْحِ ثُمَّ جَلَسُوا يَذْكُرُونَ اللَّهَ حَتَّى طَلَعَتِ الشَّمْسُ فَأُولَئِكَ أَسْرَعُ رَجْعَةً وَأَفْضَلُ غَنِيمَةً
