Clipping or Pulling out Gray Hairs

“He (the Imam) (a.s.), has said, ‘The first one who noticed gray hairs was Ibrahim ‘Alayhi al-Salam, and he asked, ‘O Lord, what is this?’ He said, ‘It is light and reverence.’ He then said, ‘O Lord, increase it for me.’”

“Abu ‘Abd Allah (a.s.), has said, ‘People did not grow gray hairs but Ibrahim ‘Alayhi al- Salam, found gray in his beard and asked, ‘O Lord, what is this?’ He said, ‘It is reverence.’ He then said, ‘O Lord, increase my reverence.’”
