Sahih al-Bukhari Book 78, Hadith 2
A man came to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! Who is more entitled to be treated with
the best companionship by me?" The Prophet (ﷺ) said, "Your mother." The man said. "Who is next?" The
Prophet said, "Your mother." The man further said, "Who is next?" The Prophet (ﷺ) said, "Your mother."
The man asked for the fourth time, "Who is next?" The Prophet (ﷺ) said, "Your father. "
I heard Abi `Amr 'Ash-Shaibani saying, "The owner of this house." he pointed to `Abdullah's house, "said, 'I asked the Prophet (ﷺ) 'Which deed is loved most by Allah?" He replied, 'To offer prayers at their early (very first) stated times.' " `Abdullah asked, "What is the next (in goodness)?" The Prophet (ﷺ) said, "To be good and dutiful to one's parents," `Abdullah asked, "What is the next (in goodness)?" The Prophet (ﷺ) said, "To participate in Jihad for Allah's Cause." `Abdullah added, "The Prophet (ﷺ) narrated to me these three things, and if I had asked more, he would have told me more."
A man said to the Prophet, "Shall I participate in Jihad?" The Prophet (ﷺ) said, "Are your parents living?" The man said, "Yes." the Prophet (ﷺ) said, "Do Jihad for their benefit."
