24وَاخفِض لَهُما جَناحَ الذُّلِّ مِنَ الرَّحمَةِ وَقُل رَبِّ ارحَمهُما كَما رَبَّياني صَغيرًا(Irfan-ul-Quran)And always lower your arms of submissiveness and humility out of soft-heartedness for both of them and keep supplicating (Allah): ‘O my Lord, have mercy on both of them as they brought me up in (my) childhood (with mercy and clemency).’
