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].

وعن أبي هريرة رضي الله عنه أن رسول الله ﷺ قال: "أقرب ما يكون العبد من ربه وهو ساجد، فأكثروا الدعاء" ((رواه مسلم)).
