It is narrated from Sayyiduna Ka'b bin Malik (may Allah be pleased with him) that whenever the Messenger of Allah (peace and blessings be upon him) set out on a journey, he would depart on a Thursday.

In one narration, it is stated that the Prophet (peace be upon him) liked that a journey be commenced on Thursday at the beginning of the day.

The Messenger of Allah (peace be upon him) said: "O Allah! Bless my Ummah in their early mornings." And he (peace be upon him) used to send out the armies at the beginning of the day.

It is narrated from Abdullah bin Ubaid bin Nasheet, may Allah have mercy on him, that when Sayyiduna Abu Bakr Siddiq, may Allah be pleased with him, dispatched armies towards Syria, he appointed Yazid bin Abi Sufyan, Amr bin Al-Aas, Shurahbil bin Hasana, and Khalid bin Walid, may Allah be pleased with them, each over separate armies. Yazid bin Abi Sufyan, may Allah be pleased with him, was appointed as the commander over all of them. Sayyiduna Abu Bakr Siddiq, may Allah be pleased with him, himself walked with them on foot, giving them advice. Yazid said: "O Caliph of the Messenger of Allah! Either you ride, or I will get down and walk with you on foot." So Sayyiduna Abu Bakr, may Allah be pleased with him, said: "Neither will I ride, nor will I let you get down. I seek the reward of these steps in the way of Allah." Then he said: "There, many kinds of food and drink will be presented to you. When you eat, mention the name of Allah, and when you finish, say Alhamdulillah. You will meet people who have shaved their heads, their heads will be like straps, split their heads with swords. Some people you will find confined in monasteries, absorbed in worship, leave them to their state." Then he said: "Do not kill any child, woman, or old man. Do not destroy inhabited areas. Do not cut down fruit-bearing trees, or slaughter mute animals, cows, or goats except for food. Do not burn or flood palm groves. Do not commit treachery. Do not show cowardice."

A companion sought permission for jihad, so the Prophet (peace be upon him) said: "Do not be afraid, do not commit treachery, do not burn or cut down date palm trees, do not kill animals without necessity, and do not harm the Muslims."

The Messenger of Allah (peace be upon him) sent (us) on an expedition and said: "If you see a mosque or hear the call to prayer, then do not kill anyone."

Abu Salat and Abu Masafi’ (may Allah have mercy on them) narrate:“We were in Nahawand when Sayyiduna ‘Umar bin Khattab (may Allah be pleased with him) sent us this written message: Establish the prayer at its appointed time, do not turn your backs when you meet the enemy, and do not be dishonest with the spoils when you obtain them.”

The Messenger of Allah (peace and blessings be upon him) said: "The best companions are four, the best detachment consists of four hundred individuals, and the best army is of four thousand."

The Messenger of Allah (peace and blessings be upon him) said: "The best friend in the sight of Allah is the one who is best to his friend, and the best neighbor is the one who is best to his neighbor."

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that Allah, the Blessed and Exalted, spoke to the western sea and said: "O sea! I have created you, and I have made your creation excellent, and I have placed much water in you, and I will make some of My servants ride upon you who will proclaim My greatness (takbir), praise (tahmid), glorification (tasbih), and declaration of My oneness (tahlil). So how will you treat them?" The sea replied: "I will drown them." Allah the Exalted said: "I will confine your wrath within your shores, and I will lift those servants of Mine upon My hands." Then Allah the Exalted spoke to the eastern sea and said: "O sea! I have created you, and I have made your creation excellent, and I have placed much water in you, and I will make some of My servants ride upon you who will proclaim My greatness, praise, glorification, and declaration of My oneness. So how will you treat them?" The eastern sea replied: "I will join them in glorifying, praising, and declaring Your oneness, and I will carry them upon myself, within myself, and upon my back." Allah the Exalted, in return, granted it the reward of jewels and game.
