Shall I make it upon her behalf?’ He said: ‘Don’t you think that if your mother owed a debt, you would pay it off on her behalf?’ He said: ‘Yes.’ He said: ‘The debt owed to Allah is more deserving of being paid off.” (One of the narrators) Sulaiman said: “When we were sitting and Muslim narrated this Hadith, Al-Hakam and Salamah bin Kuhail both said: ‘We heard Mujahid quote this from Ibn Abbas.”
