(Imām Bukhārī narrates): Muhammad bin Ar'arah narrated to us, he said: Shu'bah narrated to us from Sulaiman from Muslim al-Batin from Sa'id bin Jubair from Ibn Abbas from the Prophet ﷺ, he said:
No deed is more excellent than the saying of these Takbirs in these ten days of Dhul Hijjah. The Companions asked: Not even jihad? He said: Not even jihad, except a man who put his life and wealth at risk and returned with nothing.
