Bismillahi Al-Rahmani Al-Rahim
Calling Someone Ayah
Is it permissible to call someone ayah, or sign, of Allah?
Ibn Rajab referred to Imam Ahmad (Allah have mercy upon him) as an ayah, a diving sign. He did this in his small essay Al-Radd `Ala Man Ittaba` Ghayr Al-Madhahib Al-Arba`. Given Ibn Rajab's standing in the Hanbali madhhab, this strongly implies that this is permissible.
And Allah knows best.
