This extra-ordinary care shown by Allah Ta’ ala to free his prophet from this blame points out to the fact that Allah Ta'ala keeps even the bodies of His prophets generally free and pure from defects that appear repulsive and undignified - as it stands proved from the Hadith of Bukhari that all prophets are lineally high-born. The reason is that it would be hard to agree to listen to, accept and follow someone from the line and family regarded by people as customarily low. Similarly, the history of prophets does not bear out that any prophet was blind, deaf, dumb or handicapped. As for the case of Sayyidna Ayyub (علیہ السلام) it cannot be used to raise any objection, for what happened to him was the dictate of Divine wisdom, a particular trial, a temporary discomfort which was eliminated later on. Allah knows best.
