(Second chain) It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: Indeed, Jibreel (peace be upon him) was stuffing clay into Pharaoh’s mouth, fearing that he might utter "La ilaha illallah" (There is no god but Allah).

Brief Explanation
Benefits: … The end of evil people is also evil. The fundamental law of Allah Ta’ala is that a person dies in the same manner as he lived his life. The souls of those who were accustomed to performing abundant prostrations (sujud) during their lives departed while they were in prostration, and those who were devoted to evil had to accept the message of death while in a state of wrongdoing. The life of Pharaoh was filled with severe examples of rebellion and arrogance, so his end also had to be in accordance with that.
Further details of this have already been explained in Hadith number (8633).
