Sayyiduna Zaid bin Thabit (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) was having me write this verse: "The believers who sit (at home) without any excuse are not equal to those who strive in the way of Allah with their lives and wealth." Meanwhile, Ibn Umm Maktum (may Allah be pleased with him) came and said, "O Messenger of Allah! If I had the ability, I would certainly participate in jihad," and he was a blind man. Then Allah began to send revelation to His Messenger (peace and blessings be upon him). At that time, the thigh of the Prophet (peace and blessings be upon him) was resting on my thigh, and due to the effect of the revelation, his thigh became so heavy that I feared my thigh would be crushed. After that, when that state was lifted from the Prophet (peace and blessings be upon him), Allah revealed: "Except those who are excused." (For example, the blind, the lame, the disabled, etc.)

Narrated Anas (may Allah be pleased with him): The Messenger of Allah (peace and blessings of Allah be upon him) went towards the trench (which was being dug around Madinah). He saw that the Muhajirun and Ansar were digging the trench early in the cold mornings. They did not have any slaves to do this work for them. When the Prophet (peace and blessings of Allah be upon him) saw their distress and hunger, he recited this verse: "O Allah! The real goodness is the goodness of the Hereafter, so bestow Your blessings upon the Muhajirun and Ansar." In response, the Muhajirun and Ansar said: "We are those who have pledged allegiance to Muhammad (peace and blessings of Allah be upon him) on the condition that we will continue to strive in Jihad as long as there is life in our bodies."

Sayyiduna Anas (may Allah be pleased with him) narrates in one narration that (in the Battle of Khandaq, the Muhajirun and Ansar used to) say: "We are those who pledged allegiance to Muhammad (peace be upon him) on the condition that as long as there is life in our bodies, we will continue to strive (in jihad)." So the Noble Prophet (peace be upon him) would reply to them: "O Allah! True goodness is only the goodness of the Hereafter, so bless the Muhajirun and the Ansar."

Narrated Al-Bara' bin 'Azib (may Allah be pleased with him): I saw the Prophet (peace and blessings of Allah be upon him) on the day of the Battle of Ahzab carrying earth, and the dust had covered the color of his stomach, and he was saying: "O Allah! If it were not for You, we would not have been guided, nor would we have given charity, nor prayed. So send down tranquility upon us, and make our feet firm when we meet the enemy. Indeed, those people have rebelled against us. Whenever they intend mischief, we do not obey them."

Narrated Anas bin Malik (may Allah be pleased with him): When we returned from the Battle of Tabuk with the Prophet (peace and blessings of Allah be upon him), he said: "Some people have remained behind in Madinah, but there is no mountain pass or valley which we crossed except that they were with us (in reward). They were held back by a (valid) excuse."

Narrated Abu Sa'id Al-Khudri (may Allah be pleased with him): I heard the Prophet (peace and blessings of Allah be upon him) say: "Indeed, whoever fasts for one day in the way of Allah (i.e., in jihad), Allah will distance his face from the Hellfire by a distance of seventy years."

Narrated from Sayyiduna Zaid bin Khalid Al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever equips a warrior in the way of Allah, it is as if he himself has fought, and whoever looks after the family of a warrior in the way of Allah in his absence, it is as if he himself has fought."

Narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet Muhammad (peace and blessings be upon him) in Madinah would not visit anyone’s house except that of Umm Sulaym and his noble wives. So someone asked the Prophet (peace and blessings be upon him) the reason for this, and he (peace and blessings be upon him) replied:“I feel compassion for her; her brother was martyred along with me.”

Narrated from Sayyiduna Anas (may Allah be pleased with him) that he went to Thabit bin Qais (may Allah be pleased with him) and he was applying perfume with both his thighs uncovered. Sayyiduna Anas (may Allah be pleased with him) asked, "O uncle! What is preventing you (from the battle)?" He replied, "O son of my brother! I am coming just now." Then he continued applying perfume. Then he came and sat among the (fighters). Then it was told that in this battle the Muslims suffered a slight defeat, so Thabit (may Allah be pleased with him) said to the people, "Move aside, give us space, we will fight the disbelievers. We did not do this in battle with the Messenger of Allah (peace and blessings of Allah be upon him); rather, we used to stand firm and fight. You have given your enemies a bad habit (by fleeing)."

Narrated Jabir (may Allah be pleased with him): The Prophet (peace and blessings of Allah be upon him) said during the Battle of Ahzab, "Who will bring me news of the enemy?" Zubair (may Allah be pleased with him) said, "I will (bring it)." Then the Prophet (peace and blessings of Allah be upon him) again said, "Who will bring me news of the enemy?" He again said, "I (will bring it)." So the Prophet (peace and blessings of Allah be upon him) said, "Every prophet has a disciple, and my disciple is Zubair (may Allah be pleased with him)."
