In the Qur'an, Allah instructs Muhammad to ask forgiveness for his sin
So know, [O Muhammad], that there is no deity except Allah and ask forgiveness for your sin and for the believing men and believing women. And Allah knows of your movement and your resting place.. Surat Muhammad 47:19
My question is, does the Qur'an or hadith specify which sin(s) Muhammad committed? (If he committed sin(s)?)
