رَبِّ ارْحَمْهُمَا كَمَا رَبَّيَانِي صَغِيرًا.
My Lord, have mercy upon them [my parents] as they brought me up [when I was] small.
Rabbirhamhuma kama rabbayani ṣaghira.
This supplication suggests that the more parents do to raise their children, teach them manners, and give them a sound religious upbringing, the more those children become indebted to their parents and should, therefore, supplicate for them as much as possible. In fact, this suggests that anyone who plays a role in someone’s upbringing, nurturing, and mentoring, such as teachers, other members of the family or neighbors, also deserves special prayers and supplications.
