Is it obligatory for a father to marry off his son?

Question : The ruling on a son's marriage depends on whether the father fears for his son's livelihood or not. If he fears for his livelihood, then working becomes obligatory. If he does not fear for it, then working is not obligatory.

Answer : No, because the mahr (bridal gift) is intentional. Marrying off the son is obligatory in every case. However, regarding the son, it is he who determines the details. As for the father, if the son asks his father to marry him, it is obligatory for his father to marry him, whether he fears fitnah (trial, discord or temptation) or not.
