It is narrated from Hazrat Ma'n bin Abdur Rahman that a person named Shaiban went for jihad towards the land of Syria. His father was old, and in his son's memory, he recited verses: "O Shaiban! You do not know how many nights have passed over me after you, in which I remembered you, and your memory is beloved to me. Since you left me, a person standing near me seems like two people. O Shaiban, you are with those armies who spend their nights and days in such a state that they are victims of hardship." When these verses reached Hazrat Umar (may Allah be pleased with him), he called his son back.
