It is narrated from Sayyiduna Umayr bin Qatadah (may Allah be pleased with him) that he said: There was a matter (a question) in my heart, and I was grieved that I had not been able to ask the Messenger of Allah (peace and blessings be upon him) about it, nor had I heard anyone else ask him about it. So I kept waiting for a (suitable) time. One day I came to him (peace and blessings be upon him) while he (peace and blessings be upon him) was performing ablution, and I found him (peace and blessings be upon him) in two states in which I loved to find him (peace and blessings be upon him): I found him (peace and blessings be upon him) free and in a pleasant mood. So I said: "O Messenger of Allah! Do you permit me to ask you something?" He (peace and blessings be upon him) said: "Yes, ask whatever comes to your mind." I said: "O Messenger of Allah! What is faith?" He (peace and blessings be upon him) said: "Generosity and patience." I said: "Which believers are the best in faith?" He (peace and blessings be upon him) said: "Those who are best in character." I said: "Which Muslims are the best in Islam?" He (peace and blessings be upon him) said: "The one from whose tongue and hand (from any harm of them) the other Muslims are safe." I said: "Which jihad is the most virtuous?" He (peace and blessings be upon him) lowered his blessed head and remained silent for so long that I began to fear that I had burdened him (peace and blessings be upon him), and I began to wish that I had not asked him (peace and blessings be upon him) this question, because only the day before I had heard him (peace and blessings be upon him) saying: "The greatest wrongdoer among the Muslims is the Muslim who asked about something that had not been made unlawful for them, and then it was made unlawful for them because of his question." So I said: "I seek refuge with Allah from the anger of Allah and the anger of His Messenger." Then he (peace and blessings be upon him) raised his blessed head and said: "What did you ask?" I said: "Which jihad is the most virtuous?" He (peace and blessings be upon him) said: "Speaking a word of justice before a tyrannical ruler." The narrator Abu Badr, who narrates from Abdullah bin Ubayd bin Umayr, is named Bashshar bin al-Hakam. He is a shaykh from Basrah, and he has narrated several hadiths from Thabit al-Bunani.
