H 1313 "The Messenger of Allah, praise and peace be upon him, was asked, 'Which action is best?' He answered, 'To believe in Allah and His Messenger.' Then he was asked, 'And thereafter?' He replied, 'To believe in Allah and His Messenger.' He was further asked, 'And thereafter?' He responded, 'Fighting in the Way of Allah.' He was asked once more, 'And after that?' He replied, 'Pilgrimage free of vice and defect.'" R 1313 Bukhari and Muslim with a chain up to Abu Hurairah who related that the Messenger of Allah, praise and peace be upon him, said this.
1287- وعن أَبي ذرّ رضي الله عنه ، قَالَ : قُلْتُ : يَا رسول الله ، أيُّ العَمَلِ أفْضلُ ؟ قَالَ : "الإيمَانُ بِاللهِ ، وَالجِهَادُ في سَبِيلهِ" متفقٌ عَلَيْهِ .
