How to raise the hands after the takbirs in prayer, and how the worshipper should stand in congregational prayer?

The Shaykh : Before your question, I want to remind you of two matters that many people neglect. First: when they raise their hands with the takbirs, they do it like this. You must raise them and face the qiblah with both palms. This is one point. The other is that when you stand in the row with the congregation, you must align your feet in two parallel lines, not like this. By doing so, you are able to achieve the sunnah (recommended practice) that the Companions followed in aligning their feet and shoulders. This is a reminder, and a reminder benefits the believers.
