From the life of Hazrat Umar (ra) bin Khattab
The siege of Alexandria continued for nine months. Hazrat Umar (ra) was worried and wrote a letter saying, “Perhaps you have become driven by luxuries there otherwise obtaining victory should not have taken this long. Along with this message, deliver a speech to the Muslims about jihad and then level an attack.”
After reading out this letter from Hazrat Umar (ra), Hazrat Amr (ra) bin al-Aas called Hazrat Ubadah (ra) bin Samit and handed him the flag. The Muslims carried out an intense attack and thus conquered the city.
