Assalamu alaikum.Thank you for question No.2112647.My question was not about when divorce can take place.My question was when after Hajjathul Wadha when companions(Allah be pleased with them)went to different parts of the world,those who were married or had children did they leave them?or did they take their families with them?or only those who were not married go for preaching?Those who,if they left their wives,did these wives remarry?Was Salaam.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

First of all, it should be mentioned that the books of biographies and history prove that many companions who travelled to Greater Syria did so either for the purpose of fighting in the cause of Allaah or preaching His religion. They travelled to Iraq and to other countries along with all their wealth and families. For instance the biographers mentioned that Al-Haarith Ibn Hishaam travelled during the reign of 'Umar with his family and wealth from Makkah to Greater Syria, and then the people of Makkah followed him. Thereupon, he said to them: 'If I were to choose between two places, I would never have left Makkah, but I am travelling for Allaah's cause.' Thus, he was fighting in the cause of Allaah in Greater Syria until he died upon doing good deeds.

Similarly, Suhayl Ibn 'Amr travelled along with all his family, and there were many companions who did so. Nonetheless, if it is reported that a given companion travelled on his own without taking his family, there is no doubt that he had left for them a person who would take care of them and spend on them, until he returns.

Finally, it should be noted that knowing the answer to this question does not entail any action. What benefit would the questioner get from knowing such an answer? Rather, a Muslim should spend his time and effort in seeking knowledge which necessitates action and which would get him closer to Allaah. The companions were most knowledgeable about the obligations which Allaah required from them toward caring, providing for, and guarding the welfare of their families. 

Allaah Knows best.
