عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: أَقْرَبُ مَا يَكُونُ الْعَبْدُ مِنْ رَبِّهِ وَهُوَ سَاجِدٌ فَأَكْثِرُوا الدُّعَاءَ
Sayyiduna Abu Hurairah (may Allah be pleased with him) says: The servant is closest to his Lord while in the state of prostration, so make abundant supplication in it.
