Answer
(Fatwa: 207/197=B)
It is un-Islamic to regard going to tabligh for these durations as un-Islamic, what they say is wrong. Actually, going in tabligh is for personal and social reform. It aims at gaining strength in religion, acting upon the commands of Allah and his Messenger and making efforts for reform and success of all Muslims rather entire humanity. Are all these matters un-Islamic? May Allah grant healthy brain and right understanding, amen!
