The Book of Du'a (Supplications)
Some Verdicts Pertaining to Supplications
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: أَقْرَبُ مَا يَكُونُ الْعَبْدُ مِنْ رَبِّهِ وَهُوَ ساجد، فَأَكْثرُوا الدُّعَاء ((رَوَاهُ مُسلم)).
Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "A slave becomes nearest to his Rubb when he is in prostration. So increase supplications in prostrations." [Muslim].
