عَنْ شُعْبَةَ قَالَ: سَمِعْتُ أَبَا إِسْحَاقَ يُحَدِّثُ أَنَّهُ سَمِعَ رَجُلًا مِنْ بَنِي تَمِيمٍ قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ عَنْ قَوْلِ الرَّجُلِ بِإِصْبَعِهِ يَعْنِي هَٰكَذَا فِي الصَّلَاةِ قَالَ ذَٰكَ الْإِخْلَاصُ
Sayyiduna Wa’il bin Hujr Hadhrami (may Allah be pleased with him) describes the manner of the prayer of the Messenger of Allah (peace and blessings be upon him): Then he sat down, spread his left foot, placed his left palm on his thigh and left knee, and raised his right elbow from his left thigh, then closed his fingers and made a circle. And in one narration: he made a circle with the thumb and middle finger and pointed with the index finger. Then when he raised his finger, I saw him moving it and supplicating with it.
