Sayyidah al-Shifa' (may Allah be pleased with her) narrates: I heard the Prophet (peace and blessings be upon him) when a man asked him: Which deed is most virtuous? He said: "Faith in Allah Almighty, jihad in His path, and an accepted (mabrur) Hajj."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are thiqat (trustworthy).
