أحسن الله إليك I wanted to ask, I noticed some reciters always prolong or even stop at the word Allah in an Aya, despite there not being any MADD. Would you please clarify this for me, is it an unwritten rule? or is it just a style of recitation and should I imitate it?

Ustadh AbdulAziz al-Haqqan

There is a natural madd in the word Allah, as an alif is pronounced between the lam and the ha even though it is not written.
