Kallab bin Talid, "who belonged to Banu Sa'd bin Layth," was once sitting with Hazrat Sa'id bin al-Musayyib when a messenger from Nafi' bin Jubayr came to him and said, "Your nephew sends you greetings and asks about that hadith which you mentioned to me regarding Hazrat Asma bint Umais (may Allah be pleased with her)?" Sa'id bin al-Musayyib replied that Hazrat Asma bint Umais (may Allah be pleased with her) told me that she heard the Prophet (peace and blessings be upon him) say: "Whoever endures the hardships and difficulties of Madinah with patience, I will intercede and bear witness for him on the Day of Resurrection."
