"Then he placed the turban on Aaron's head and set the gold plate, the sacred diadem, on the front of it, as the Most High commanded Moses" (Levi 8:9).
Headcovering has always been an Israel custom. In fact, both Judaism and Islam took this custom from the Israelites. Hebrew Israelites are allowed to wear turban, kofi and similar headcoverings. Both, women and men must cover their heads while praying. Christians based their teachings on Paul of Tarsus who claim that only females should cover their heads. We, the Israelites do not believe so;we believe that both male and females must cover their heads, specially when praying.
Praying Towards Jerusalem
Moreover all Israelites shall pray toward Jerusaelm. When Solomon dedicated the temple(1King 8),he specifically asked that the Most High would answer the pray of any Israelite who pray toward Jerusalem. Daniel himself prayed towards Jerusalem.
Now when Daniel knew that the writing was signed, he went into his house; and his windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime. (Daniel 6:10)
Praying with feet uncovered
Although this is not enforced, we always advise that all Hebrew Israelites to pray with their feet bared just as the Most High ordered Moses to remove his sandals before the burning bush. Removing the sandals mean that you acknowledge that the presence of the Most High is there and that the place where you are is a Holy.
Should you pray standing or on your knees
As Israelites wer pray both standing and on our knees. However, we do not pray with our face toward the ground as the muslims do. We pray standing with our palm open and face toward Jerusalem and in our knees but still face towards Jerusalem
