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)
قَالَ رَسُولُ اللهِ ﷺ قَالَ رَبُّكُمْ إِنْ تَقَرَّبَ عَبْدِي مِنِّي شِبْرًا تَقَرَّبْتُ مِنْهُ ذِرَاعًا وَإِنْ تَقَرَّبَ مِنِّي ذِرَاعًا تَقَرَّبْتُ مِنْهُ بَاعًا وَإِنْ أَتَانِي مَاشِيًا أَتَيْتُهُ هَرْوَلَةً
