It is narrated from Hazrat Bukair (may Allah have mercy on him) that when the Messenger of Allah (peace and blessings be upon him) appointed Sayyiduna Usama bin Zaid (may Allah be pleased with them both) as commander, people objected. So the Messenger of Allah (peace and blessings be upon him) said: "You speak about Usama being young in age, and you spoke in the same way about his father. By Allah! He is worthy of leadership." Hazrat Bukair (may Allah have mercy on him) says: I was informed that Hazrat Ubaidah bin Sufyan (may Allah have mercy on him) said: "I hope this decision remains in effect till today." It is narrated from Sulaiman bin Yasar (may Allah have mercy on him) that the Messenger of Allah (peace and blessings be upon him) appointed Usama (may Allah be pleased with him) as commander over an army and ordered that the village of Yabna be burned. When the army set out, Usama delayed a little until the Messenger of Allah (peace and blessings be upon him) passed away. Then Usama came to Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) and said: "What do you command me?" He replied: "Act upon what the Messenger of Allah (peace and blessings be upon him) commanded you; I will neither add to it nor subtract from it." People said: "If you send Usama and take the nearby people with him, the Bedouin Arabs will become apostates and attack Madinah." Sayyiduna Abu Bakr Siddiq (may Allah be pleased with him) said: "By Allah! Even if wild beasts devour me, I will not revoke the command of the Messenger of Allah (peace and blessings be upon him). Go, Allah will help us. But if you wish, you may keep Sayyiduna Umar bin Khattab (may Allah be pleased with him) with you." Usama said: "I went to Umar (may Allah be pleased with him) and gave him permission." So Sayyiduna Umar (may Allah be pleased with him) said: "May Allah have mercy on you."

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) stood on the pulpit and said: "Some people have criticized Usama's leadership just as they had previously criticized his father's leadership, even though both of them were worthy of it."

Hazrat Abu Malik (may Allah have mercy on him) said: The first verses of Surah Bara’ah, more than forty verses, were revealed from {انْفِرُوا خِفَافًا وَثِقَالًا} to {إِنْ كُنْتُمْ تَعْلَمُونَ}.

Hazrat Umar bin Khattab (may Allah be pleased with him) wrote: "Keep a desert as a distance between yourselves and the enemy."

It is narrated from Hazrat Abu Duhha, may Allah have mercy on him: Regarding the martyrs of Uhud, this verse was revealed «وَلَا تَحْسَبَنَّ الَّذِينَ قُتِلُوا فِي سَبِيلِ اللَّهِ أَمْوَاتًا بَلْ أَحْيَاءٌ عِندَ رَبِّهِمْ يُرْزَقُونَ» and also this «وَيَتَّخِذَ مِنْكُمْ شُهَدَاءَ» about them. On that day, seventy people were martyred. Four were from the Muhajireen: Sayyiduna Hamza bin Abdul Muttalib (may Allah be pleased with him), Sayyiduna Mus'ab bin Umair (may Allah be pleased with him), Sayyiduna Shamas bin Uthman (may Allah be pleased with him), and Sayyiduna Abdullah bin Jahsh (may Allah be pleased with him). The rest were all from the Ansar.

It was asked from Sayyiduna Salim bin Abdullah (may Allah be pleased with him): If there is a wound on the clothes or body and there is blood on it, will the prayer be valid? He replied: "No."

It is narrated from Hazrat Ikrimah (may Allah have mercy on him): When this verse was revealed «إِلَّا تَنْفِرُوا يُعَذِّبْكُمْ عَذَابًا أَلِيمًا وَيَسْتَبْدِلْ قَوْمًا غَيْرَكُمْ» , the hypocrites said: "There are some people who did not go out for jihad, so have they perished?" Whereas there was a group that stayed behind to acquire knowledge of the religion «لِيَتَفَقَّهُوا فِي الدِّينِ» , and about them Allah said «وَالَّذِينَ يُحَاجُّونَ فِي اللَّهِ مِنْ بَعْدِ مَا اسْتُجِيبَ لَهُ» .

It is narrated from Sayyiduna Thawban (may Allah be pleased with him): He said, "Sharpen your sword." It was asked: "Why, O Abu Abdullah?" He replied, "Cowardice has been placed in your hearts and fear has been removed from the hearts of your enemies." It was asked: "Why is that?" He said, "Because of love for the world and dislike of death." Glad tidings are for the one whose tongue remains silent, who weeps over his sins, and for whom his house is sufficient.

Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: The Messenger of Allah (peace and blessings be upon him) said: "The voice of Abu Talhah in the army is better than a group." He would sit kneeling in front of the Prophet (peace and blessings be upon him) and say: "My face is a shield for your face, and my life is sacrificed for your life."

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him): People asked Sayyidah Asma (may Allah be pleased with her): "Which was the hardest day upon the Messenger of Allah (peace and blessings be upon him)?" She replied: "I think I remember that day when he was in the mosque and some of those people were present." They began to say: "He says this and that which we dislike." So they came to him as a group. They said: "Do you say this?" He replied: "Yes." And he would not hide anything from them. Then they seized him. A caller came to my father and said: "Go to the aid of your companion." My father came running. He had hair in braids. And he called out: "Do you kill a man because he says: 'My Lord is Allah'?" Then they became occupied with him and turned towards my father. He came to us and kept saying: "You are blessed, O Possessor of Majesty and Honor." He had a braid on his head. He would do like this with his hand.
