Messenger of Allah said: "They said: 'O Messenger of Allah, whom should I treat kindly?' He said: 'Your mother.' He said: 'Then who?' He said :'Your mother." He said: 'Then who?' He said: 'Your father'. He said : 'Then who?' He said: 'The next closest and the next closest.'" (Using translation from Ibn Mājah 3658)
قُلْتُ يَا رَسُولَ اللَّهِ مَنْ أَبَرُّ؟ قَالَ «أُمَّكَ» قُلْتُ ثُمَّ مَنْ؟ قَالَ «أُمَّكَ» قُلْتُ ثُمَّ مَنْ؟ قَالَ «أَبَاكَ» قُلْتُ يَا رَسُولَ اللَّهِ ثُمَّ مَنْ؟ قَالَ «ثُمَّ الْأَقْرَبَ فَالْأَقْرَبَ»
