Re: what are the chances that your BIL fancies you?
This is a delicate situation.
Nabi-Pak, in a sahih bukari hadith, on being asked about the 'brother in law'' said:
''The Brother In Law is Death''
Also in sahih bukari he said:
''Im am not leaving behind any trial or tribulation bigger, for the men of my umma than that of women''.
Now you all do the maths...
