Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that I asked the Noble Prophet (peace and blessings be upon him): Which deed is most beloved to Allah Almighty? He (peace and blessings be upon him) replied: Performing prayer at its appointed time. I asked: Then which? He replied: Treating parents with goodness. I asked: Then which? He (peace and blessings be upon him) replied: Striving in the path of Allah. Sayyiduna Ibn Mas'ud said: The Noble Prophet (peace and blessings be upon him) informed me of this in detail, and if I had asked further, he (peace and blessings be upon him) would have told me even more (but I remained silent out of respect).
