It should be noted that according to the Most likely view in Hanafi jurisprudence, the time for the Asr prayer begins after the "Misl e Sani" i.e. when the shadow of everything (except the shadow of the time of fall) become double.Therefore Asar should be offered only after the "Misl e Sani".
Since it is permissible to offer the Asr prayer after the "Misl e Awal" in three other jurisprudence along with Sahibain (Two Hanfi Imams),
it is permissible to offer the Asr prayer After "Misl e Awal", if there is any excuse or compulsion, but it is not allowed to make it (performing Asar after "Misl e Awal") a routine.
In normal circumstances, it is necessary to perform Asr prayer after "Misl e Sani", because this is the most likely view according to the Hanafi Jurisprudence.
Hence, if there is a mosque nearby your residency, where according to the Hanafi Jurisprudence, Asr prayer is offered , then you should offer with them after "Misl e Sani" .
And if there is no such mosque, and in that place everyone offer the Asr prayer after the "Misl e Awal", then it is better than abandoning the congregation to perform the Asr prayer together with them in the "Misl e Awal".
Yes! If for some reason the congregation is left, then Asr prayer should be offered after the "Misl e Sani" while praying individually.
