It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade solitude, that is, for a man to spend the night alone and to travel alone.

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "If people knew what (harm) there is in solitude, then no traveler would set out alone at night."

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "A single traveler is a devil, two travelers are also devils, but when there are three travelers, they form a caravan."

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says: A man left from Khaybar, two men started following him, and there was another behind them who was telling them: "Return, return." (Until) he made them return, then he joined the first man and informed him that those two were devils, I kept following them until I made them return. When you reach the Messenger of Allah (peace and blessings be upon him), convey my greetings to him and inform him that I am collecting charity here; if you (O Prophet) are worthy of it, we will send it. That man reached Madinah and conveyed his message to the Prophet (peace and blessings be upon him). At that time, the Prophet (peace and blessings be upon him) forbade seclusion (being alone).

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates that a man left from Khaybar, two men started following him, and another man followed those two. The last man kept telling the two: "Turn back," until he caught up with them and made them return. Then he caught up with the first man and said to him: "Those two were devils; I kept distracting them until I made them return." When you reach the Messenger of Allah (peace and blessings be upon him), convey my greetings to him and inform him that I am collecting zakat here; if it is suitable for you, we will send it. When that man reached the Prophet (peace and blessings be upon him), he narrated the whole incident. At that time, the Prophet (peace and blessings be upon him) forbade seclusion (with non-mahram women).

Sayyiduna Sakhr bin ‘Ailah (may Allah be pleased with him) says that when Islam appeared, some people from the Banu Sulaym tribe fled, leaving their lands. I took possession of them, and then they (the people) became Muslim (and returned), and the dispute was brought to the Prophet (peace and blessings of Allah be upon him). The Prophet (peace and blessings of Allah be upon him) returned the lands to them and said:“When a person becomes Muslim, he has a greater right to his land and wealth.”

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Prophet, peace and blessings be upon him, said: "When you intend to leave your house, perform two rak‘ahs of prayer, for they will prevent you from leaving in a bad way. And when you intend to enter your house, perform two rak‘ahs of prayer, for they will prevent you from entering in a bad way."

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When the treasures of Persia (Iran) and Rome are conquered for you, what kind of people will you be at that time?" Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) said: We will say what Allah Almighty has commanded us. The Messenger of Allah (peace and blessings of Allah be upon him) said: "Is there anything else? First, you will compete with each other to take your share, then you will envy one another, then you will sever ties and become enemies of one another, then you will harbor aversion towards each other and adopt such (evil habits), and then you will attack the homes of the Muhajirun and make them fight one another."

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When three people are on a journey, one of them should lead the others in prayer, and the one most deserving of this is the one who knows the most of the Qur'an by heart."

It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that when the Messenger of Allah (peace and blessings be upon him) passed by the stone dwellings (the abodes of Thamud), he said: "Enter the places where the previous nations were punished while weeping. If you cannot weep, then do not enter them, lest you be afflicted with the same punishment." Then he covered himself with his cloak while sitting on his mount.
