Prostration and its Excellence - Section 1
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «أَقْرَبُ مَا يَكُونُ الْعَبْدُ مِنْ رَبِّهِ وَهُوَ ساجد فَأَكْثرُوا الدُّعَاء» . رَوَاهُ مُسلم
Abu Huraira reported God’s Messenger as saying, “The nearest a servant comes to his Lord is when he is prostrating himself, so make supplication often.” Muslim transmitted it.
