Is it recommended to indicate with the finger in prayer?

The questioner : If one is unable to indicate with the head, and we said that he does not indicate with the eye, does he indicate with the finger?

The Shaykh : No, he does not face with the finger. Why? Because no hadith has been reported from the Prophet (peace and blessings be upon him)

The questioner : Yes,

The Shaykh : He does not indicate with his finger because no evidence has been reported for it, and no one among the scholars has said so. Acts of worship are based on restriction; if they are reported from the Shari'ah, they are valid, otherwise they are not.
