عَنْ أَبِي هُرَيْرَةَ ـ رضى اللّٰه عنه ـ قَالَ قَالَ النَّبِيُّ صلى اللّٰه عليه وسلم: يَقُولُ اللّٰهُ تَعَالَى أَنَا عِنْدَ ظَنِّ عَبْدِي بِي، وَأَنَا مَعَهُ إِذَا ذَكَرَنِي، فَإِنْ ذَكَرَنِي فِي نَفْسِهِ ذَكَرْتُهُ فِي نَفْسِي، وَإِنْ ذَكَرَنِي فِي مَلأٍ ذَكَرْتُهُ فِي مَلأٍ خَيْرٍ مِنْهُمْ، وَإِنْ تَقَرَّبَ إِلَىَّ بِشِبْرٍ تَقَرَّبْتُ إِلَيْهِ ذِرَاعًا، وَإِنْ تَقَرَّبَ إِلَىَّ ذِرَاعًا تَقَرَّبْتُ إِلَيْهِ بَاعًا، وَإِنْ أَتَانِي يَمْشِي أَتَيْتُهُ هَرْوَلَةً.
Hazrat Abu Hurairahra narrated:
The Prophet, peace and blessings of Allah be upon him, said, “Allah the Exalted says: ‘I am as My servant expects Me to be, and I am with him when he remembers Me. If he remembers Me within himself, I remember him within Myself; and if he remembers Me in a gathering, I remember him in a gathering better than theirs. If he draws near to Me by a hand’s span, I draw near to him by an arm’s length; if he draws near to Me by an arm’s length, I draw near to him by a fathom’s length; and if he comes to Me walking, I go to him running.’”
(Sahih al-Bukhari, Kitab at-tawhid, Bab qawlillahi ta‘ala ‘wa yuhazzirukumullahu nafsah, Hadith 7405)
