Salafis deny the Omnipresence of Allah Ta'ala.

Answer

The Qur'aan Majeed instructs that you should not argue with morons. Laymen and even molvis who lack adequate knowledge in these kinds of drivel, should respond as the Qur'aan instructs:

"For us are our deeds and for you are your deeds.

There is no scope for dispute between us and you.

Allah will gather us (on the Day of Qiyaamah and decide the issues). Unto Him is the Return.

Those who argue about Allah after He (and His Ahkaam)

have been accepted, their argument is baseless by their Rabb. On them is Wrath and for them there is a dreadful punishment."

(Ash-Shuraa, Aayats 15 & 16)

Do not become entangled with obstinate morons. There is no goodness in disputing with them. It only causes more ill-feeling. Refer them to the Ulama.
