Fath al-Rabbani

Sayyidah Aisha (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) would begin the prayer with the takbeer and the recitation with {اَلْحَمْدُ لِلّٰہِ رَبِّ الْعٰلَمِیْنَ}, when he would bow (in ruku‘), he would neither raise his head too much nor lower it too much, but would keep it in between. When he would raise his head from ruku‘, he would not go into prostration (sajdah) until he stood up straight. When he would raise his head from prostration, he would not perform the (second) prostration until he sat up straight. After every two rak‘ahs, he would recite "At-tahiyyatu lillah…". He (peace and blessings be upon him) disliked that anyone should spread his arms like a beast during prostration. When he sat, he would spread his left foot and keep his right foot upright. He (peace and blessings be upon him) forbade the sitting posture of Satan and would end the prayer with salam.
