It is narrated from Abu Qilabah (may Allah have mercy on him) that the companions of the Messenger of Allah (peace be upon him) mentioned their sons and said, "Our sons are better than us; they were born in Islam and did not associate anything with Allah at all." When this reached the Messenger of Allah (peace be upon him), he said: "Allah Almighty has sent me to the best of the Ummah. We are better than our sons, and our sons are better than our grandsons, and our grandsons are better than their sons."
