Those Muslims who have seen our Prophet sallallahu alayhi wa sallam and have died as Muslims, are known as Sahabah. Very great virtues have been mentioned with regard to them. We have to love and think good of all of them. If we hear of any dispute or conflict among them, we should regard it as a misunderstanding or a miscalculation. We should not speak any ill of them. The greatest among them are four Companions: Hadrat Abu Bakr Siddiq radiallahu anhu. He took the place of Rasulullah sallallahu alayhi wa sallam and supervised the matters of the Deen. He is therefore called the first Khalifah. He is the best person in the entire ummat. After him comes Hadrat Umar radiallahu anhu. He is the second Khalifah. After him is the third Khalifah, Hadrat Uthman radiallahu anhu. After him is the fourth Khalifah, Hadrat Aliradiallahu anhu. The status of the Sahabah is so high that even the greatest of walis cannot reach a stage equal to the lowest Sahabi. All the children and wives of the Prophet sallallahu alayhi wa sallam are worthy of respect. Among his children, Hadrat Fatima radiallahu anha has the highest status. Among his wives, Hadrat Khadija and Hadrat Aisha radiallahu anhuma have the highest status.
