Recommending supplication

Q 2: Is this Hadith mentioning some words said by the Prophet (peace be upon him) to `Umar ibn Al-Khattab, O brother, do not forget to supplicate to Allah for my sake! Sahih (authentic)? If so, we would like you to supplicate to Allah (Exalted be He) (Part No. 24; Page No. 228) to have mercy on and forgive us, our children and our spouses. Allah (Exalted be He) is Vast in His Mercy and Forgiveness.

A: It was related by Abu Dawud and Al-Tirmidhy in their Sunan (Hadith compilations classified by jurisprudential themes) that `Umar ibn Al-Khattab (may Allah be pleased with him) said, "I took the permission of the Messenger of Allah (peace be upon him) to perform `Umrah, and he gave me permission. He said to me, "O brother, do not forget to supplicate to Allah for my sake," or "O brother, supplicate to Allah for my sake when you do for yourself." `Umar said, "I would not have replaced this word for the whole world." May Allah guide us all to what pleases Him.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
