Abdullah bin Masud reported,

I asked the Prophet ﷺ, "Which deed is most beloved to Allah?"He answered, "Prayer at its appointed time."I asked, "Then what?"He said, "Kindness to one's parents."I asked, "Then what?"He said, "Striving in the path of Allah."He said, "He told me these, and had I asked for more, he would have told me more."

سألت النبي ﷺ: أي العمل أحب إلى الله؟ قال: الصلاة على وقتها، قال: ثم أي؟ قال: بر الوالدين، قال: ثم أي؟ قال: الجهاد في سبيل الله. قال: حدثني بهن ولو استزدته لزادني.
