The command to be good to one's parents begins right from the Qur'an. Allah says:
“Worship Allah and join not any partners with Him; and treat your parents with goodness…” [Quran 4:36]
The mention of servitude to parents follows immediately after servitude to Allah. SubhanAllah, the Most High could of mentioned any act after his worship, but he chose the most appropriate.
How many of us actually think in this pattern “I must worship Allah, and treat my parents with excellence”. We might get the first half right but undo the good work by neglecting the second half. Actually we shouldn't separate the two as that's what Allah commanded in the Quran because they go hand in hand.
Let's look at how our pious predecessors understood level of the mothers status:
Ibn Umar (radhi allahu anhu) saw a man carrying his mother going around the Kabah in Tawaf (circumambulation) and he asked Ibn Umar (radhi allahu anhu): “Have I fulfilled my duty towards her?” Ibn Umar replied: “Not even for one contraction! However, you have done good and Allah will reward you tremendously for the little that you could do.”
Next time you feel like ignoring, rolling your eyes or walking away at your mother's request, remember what Ibn Umar said.
