Raising the forefinger in the Tashahhud is Sunnah (supererogatory act of worship following the example of the Prophet), as it signifies Allah’s Oneness. It is optional; whoever wants to do it can do so. Such a matter should not lead to dispute and division among the seekers of knowledge. However, if a worshipper does not raise it or raises it without moving it, it is all right, and this should not necessitate objection and rejection. The Sunnah is to raise it throughout the whole Tashahhud till the person offering Salah makes Taslim (salutation of peace ending the Prayer), as a sign of Tawhid (belief in the Oneness of Allah). As for moving the forefinger, it is when making Du‘a’ (supplication) as authentically reported in the Sunnah. (Part No. 5; Page No. 369) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
