Hadith 527
Narrated `Abdullah: I asked the Prophet "Which deed is the dearest to Allah?" He replied, "To offer the prayers at their early stated fixed times." I asked, "What is the next (in goodness)?" He replied, "To be good and dutiful to your parents" I again asked, "What is the next (in goodness)?" He replied, 'To participate in Jihad (religious fighting) in Allah's cause." `Abdullah added, "I asked only that much and if I had asked more, the Prophet would have told me more."

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 Apostle anymore and if I had asked him more, he would have told me more.
