Does the pronunciation of the letter "Rā" (ر) differ, in terms of thickening (tafkheem) or thinning (tarqeeq), at the end of some Quranic words if preceded by a "yā" (ي), such as "baseer" (بصير), "khabeer" (خبير), and "qadeer" (قدير), and what is the name of this Tajweed rule?

The letter Raa (ر) in the mentioned examples, if it has a dammah (ḍammatun) or fathah (fatḥatun), is pronounced with tafkheem (heavy pronunciation) during continuous recitation for all reciters except Warsh, who pronounces it with tarqeeq (light pronunciation). As for pausing, all reciters pronounce it with tarqeeq, whether it has a dammah, kasrah (kasratun), or fathah, except in the case of a fathah with tanween (nūnātī), where it is paused upon with tafkheem for reciters other than Warsh, while Warsh pronounces it with tarqeeq. The letter Yaa (ي) after a direct kasrah is pronounced with madd (lengthening).
