The minimum time period of a salam transaction in the Hanafi mazhab
Q: I had learnt in madrasah that among the conditions for the permissibility of a salam transaction is that the period of time from the date of the sale until the date of delivery should be a minimum of one month. If the salam period is less than one month, then the transaction will not be permissible and will not be valid.
However, I was recently informed that there is another opinion in the Hanafi Mazhab, that even if the the period of time from the date of the sale until the date of delivery is less than one month, the salam transaction will be permissible provided that there is an urf of that nature in the place where one is staying. Is this the correct view in the Hanafi Mazhab?
