No. ‘Asian’ in British usage means primarily those originating from the four countries of the Indian sub-continent, not those from the Middle East. Incidentally, in Southall particularly there are very large numbers of Hindus, so this isn’t specifically a Muslim issue.

“Incidentally, in Southall particularly there are very large numbers of Hindus, so this isn’t specifically a Muslim issue....and indeed Sikhs”
Indeed. Southall is in the Borough of Ealing which included the following religious breakdown in the last Census:
Hindu: 12.4%
Muslim: 13.3%
Sikh: 23.2%
Highest proportion of Sikhs in any area of the UK I believe.
