assalamu aleykum Sometimes, some brothers who are ahlil sunna, raise their finger when taking pictures, or at the end of their talks in videos, and say "Allahu Akbar". I think, that by raising their index finger they signify that There is no deity worthy of worship except One Allah, or that Allah is Above. It has become a kind of habit for them. Is there any basis for doing this, and is there anything wrong with doing it? Jazak Allahu khair in advance.
