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 ‏"‏ ‏.‏
Translation
Abu Huraira reported Allah's Apostle (ﷺ) as saying that Allah, the Exalted and Glorious, said

When My servant draws close to Me by the span of a palm, I draw close to him by the cubit and when he draws close to Me by the cubit, I draw close to him by the space (covered) by two armspans, and when he comes to me walking, I go in a hurry towards him.
