(1) باب فَضْلُ الْجِهَادِ وَالسِّيَرِ
Narrated `Abdullah bin Masud:
I asked Allah's Messenger (ﷺ), "O Allah's Messenger (ﷺ)! What is the best deed?" He replied, "To offer the prayers at their early stated fixed times." I asked, "What is next in goodness?" He replied, "To be good and dutiful to your parents." I further asked, what is next in goodness?" He replied, "To participate in Jihad in Allah's Cause." I did not ask Allah's Messenger (ﷺ) anymore and if I had asked him more, he would have told me more.
