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. (Using translation from Muslim 2675e)
أَنَّ النَّبِيَّ ﷺ قَالَ يَعْنِي الرَّبَّ ﷻ إِذَا تَقَرَّبَ الْعَبْدُ مِنِّي شِبْرًا تَقَرَّبْتُ مِنْهُ ذِرَاعًا وَإِذَا تَقَرَّبَ مِنِّي ذِرَاعًا تَقَرَّبْتُ مِنْهُ بُوعًا أَوْ بَاعًا وَإِذَا تَقَرَّبَ مِنِّي بُوعًا أَوْ بَاعًا أَتَيْتُهُ هَرْوَلَةً
