Thereupon he said: Don't you see that if debt was due from her, would you not pay it? She said: Yes (I would pay on her behalf). Thereupon he said: The debt of Allah deserves its payment more than the payment of anyone else.

Should I complete (them) on her behalf? Thereupon he (the Holy Prophet) said: Would you not pay the debt if your mother had died (without paying it)? He said: Yes. He (the Holy Prophet) said: The debt of Allah deserves more that it should he paid.
Ibn Abbas (RA) reported Allah's Messenger (ﷺ) as saying: If anyone wants to have his deeds widely publicised, Allah will publicise (his humiliation). And if anyone makes a hypocritical display (of his deeds) Allah will make a display of him.

Ibn Abbas (RA) reported: During the pre-Islamic days women circumambulated the Ka’bah nakedly, and said: Who would provide cloth to cover the one who is circumambulating the Ka’bah so that she would cover her private parts? And then she would say: Today will be exposed the whole or the part and what is exposed I shall not make it lawful. It was in this connection that the verse was revealed: "Adorn yourself at every place of worship" (vii. 31).
