Abu Huraira reported Allah's Messenger (may peace be upon him as saying that Allah thus stated:I live in the thought of My servant as he thinks of Me and with him as he calls Me.
حَدَّثَنَا أَبُو كُرَيْبٍ، مُحَمَّدُ بْنُ الْعَلاَءِ حَدَّثَنَا وَكِيعٌ، عَنْ جَعْفَرِ بْنِ بُرْقَانَ، عَنْ يَزِيدَ، بْنِ الأَصَمِّ عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ اللَّهَ يَقُولُ أَنَا عِنْدَ ظَنِّ عَبْدِي بِي وَأَنَا مَعَهُ إِذَا دَعَانِي " .
Muslim
