عَنِ الْبَرَاءِ بْنِ عَازِبٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ إِذَا افْتَتَحَ الصَّلَاةَ رَفَعَ يَدَيْهِ حَتَّى تَكُونَ إِبْهَامَاهُ حِذَاءَ أُذُنَيْهِ
It is narrated from Sayyiduna Bara’ bin ‘Azib (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) would begin the prayer, he would raise his hands until his thumbs would be in line with his ears.
