The Virtues of Prayer - Section 1
وَعَنْ أَبِي مُوسَى قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم: «من صَلَّى الْبَرْدَيْنِ دَخَلَ الْجَنَّةَ»
Abu Musa reported God’s Messenger as saying, “He who observes the two cool times of prayer (at dawn and after nightfall) will enter paradise.” (Bukhari and Muslim.)
