After the Messenger (saw) there are numerous and elaborate Ijtihads in the time of the Sahabah. Even amongst the general masses Ijtihad was widespread and that was not considered strange because they were the original Arabs who spoke pure Arabic. Once while giving a Khutbah Umar b. Khattab tried to limit the dowry (Mahr) but a women responded from behind the lines by quoting the Ayah:

“But if you intend to replace a wife by another and you have given one of them a Qintar (of gold i.e. a great amount) as Mahr, take not the least bit of it back..” (TMQ An-Nisa: 20)

She told him from her understanding of the word Qintar which denotes many without restriction that it is not allowed for him to restrict the doweries. He (may Allah be pleased with him) said: “The woman is right and Umar is wrong.” An Ijma (consensus) of the Sahabah has taken place on the question of judging by an opinion which has been deduced from the Shar‟ai evidence i.e. they agreed on the use of Ijtihad for any incidents that took place for which no (clear) text had been found. This is what reached us in successive reports in which there is no doubt. One such report is the saying of Abu Bakr (ra) when he was asked about the Kalala. He said: “I will speak about it according to my opinion. If it is correct then it is from Allah. If it is a mistake then it is from me and from Shaytan and Allah has nothing to do with it. Kalala is the one who has no children or parents left.”36

His statement, “I will speak about it according to my opinion” does not mean this opinion is from him. Rather it meant Abu Bakr would express his opinion according to what he understood from the expression 'Kalala' in the verse of the Qur‟an:
