عَنْ مَاعِزٍ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ سُئِلَ أَيُّ الْأَعْمَالِ أَفْضَلُ قَالَ إِيمَانٌ بِاللَّهِ وَحْدَهُ ثُمَّ الْجِهَادُ ثُمَّ حَجَّةٌ بَرَّةٌ تَفْضُلُ سَائِرَ الْعَمَلِ كَمَا بَيْنَ مَطْلَعِ الشَّمْسِ إِلَى مَغْرِبِهَا
It is narrated from Sayyiduna Ma'iz (may Allah be pleased with him) that when the Noble Prophet (peace and blessings be upon him) was asked which deed is the best among deeds, he (peace and blessings be upon him) replied: To have faith in Allah Almighty, Who is One and Unique, then to strive in jihad, then Hajj Mabroor. This deed surpasses the rest of the deeds in excellence just as the distance between the rising and setting of the sun.
