1 Pointing with the index finger has a more severe effect on the devil than iron
Nafi‘ said that when ‘Abdallah bin ‘Umar ( may Allah be pleased with him ) sat during the prayer he placed his hands on his knees, pointed with his finger and gave his whole attention to it. He then said that the Messenger of Allah ( may peace and blessings of Allah be upon him ) had said, “It has a more severe effect on the devil than iron,” meaning the forefinger.
