In a Hadeeth reported in Sahih al-Bukhari:
A man came to Allah's Messenger (ﷺ) and asked, "O Prophet (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."
