Abd al-Rahman bin Sabit said: Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) sent a message to Sayyiduna Sa'id bin Amir al-Jumahi (may Allah be pleased with him): "We wish to appoint you over these people; take them to the land of the enemy and wage jihad with them." Then he mentioned a long hadith, in which there was also this: Sa'id (may Allah be pleased with him) said: "I will not lag behind the first caravan, after I heard the Messenger of Allah (peace and blessings be upon him) say about the poor Muslims: 'They will be led (to Paradise) just as pigeons are led. It will be said to them: Stop for the reckoning. They will say: By Allah, we left nothing behind for which we could be reckoned. Allah, the Mighty and Majestic, will say: My servants have spoken the truth. So they will enter Paradise seventy years before the rest of the people.'"
