Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) narrates that a man came to the Prophet (peace and blessings be upon him) and said: My sister has passed away; she had made a vow to perform Hajj (what should I do?), he (the Prophet) said: If she had a debt, would you pay it off? He said: Yes! The Prophet said: Then fulfill Allah’s right as well, for He is more deserving that His right be fulfilled.
