The song starts with a question who we should obey after Allah and rasool Allah ( the messenger of Allah) ?...... there is a hadith which explain the song:
Sahih Al-Bukhari Hadith 8.2 Narrated by Abu Huraira
A man came to Allah's Apostle and said, "O Allah's Apostle! Who is more entitled to be treated with the best companionship by me?" The Prophet said, "Your mother." The man said. "Who is next?" The Prophet said, "Your mother." The man further said, "Who is next?" The Prophet said, "Your mother." The man asked for the fourth time, "Who is next?" The Prophet said, "Your father."
With regards
Actually, I knew that Hadith...but thank you for the reminder. I love reading it. I'll have to listen to the song again. Maybe I'm just mixing up the order of the song because I thought it was said after "your mother"...
