Book Name:Dawateislami Ka Taruf
I have observed that all of you are dressed alike in white, and made Salām whilst boarding the bus. Further, much to my astonishment, even the blind people with you have worn green turbans and white dress and have grown beards.’
Listening to his comments, the Amir of the Qāfilaĥ gave him a brief introduction to the Madanī environment of Dawat-e-Islami as well as to the ‘Majlis for Special Brothers.’ He was also told about the great religious services of Amīr-e-Aĥl-e-Sunnat. He was then informed that these blind Islamic brothers are travelling with Madanī Qāfilaĥ to reform the impious Muslims (whose wicked character is an obstacle to his embracing Islam). Highly impressed by listening to this, he embraced Islam reciting Kalimaĥ.
Note: In order to read further Madanī incidents of the blind, the deaf and the dumb, get and go through the booklet ‘Goonga Muballigh’ published by Maktaba-tul-Madinah.
Preaching in Jails
Usually, those deprived of the knowledge of Quran & Sunnaĥ are deceived by their Nafs and Satan into committing different crimes like murder, terrorism, theft, robbery, fornication, narcotic-trading, gambling etc. and eventually end up in prison.
 It is not permissible to make Salām to the non-Muslims. As non-Muslims also travel by bus etc., one should make the intention of making Salām to the Muslims only whilst uttering the words of Salām in bus etc.
