Sayyidi wa sanadi Mufti Mohammad Taqi Usmani (Allah preserve him with ‘afiyet) said in discussion regarding the permissibility of praying two rakah prior to the fardh salah of maghrib,
The correct and just thing is that there is no proof (daleel) of two rakah prior to maghrib being disliked (karahiyet). And there are many proofs of its permissibility.
However, it must be taken into account that at places where there is time interval prior to congregational salah (jamah), like in the blessed Haramain, then being stubborn that I am a Hanafi and whatever happens I am not going to pray is not the proper attitude. In these situation it should be offered.
One thing that has to be always avoided is: creating fitnah.
Praying these two rakah are permissible and wherever there is time available (between adhan and jama’h) they should be offered. However, it should not be offered at places where none has even heard about this issue. Initiating these prayer in this situation will create a fitnah resulting in useless discussions.
However, mention the permissibility of this issue at an appropriate opportunity.
