The Children of Israel created the Jewish religion after they had distorted the Scripture revealed to Moses. The following verse says God will be with them for as long as they commit themselves (Sol-laa-ta) in believing God’s messenger and to lend God a loan of righteousness by upholding the covenant they made with Him.
God has taken a covenant from the Children of Israel and We appointed for them twelve disciples; and declared, “I will be with you for as long as you ‘observe your commitments and keep them pure’ (aqom-tumuz-Sol-laa-ta-wa-atai-tumuz-Zakaa) and believe My messengers and support them. And lend God a righteous loan of righteousness. I will forgive your wrongdoings, and admit you into gardens with flowing streams. Anyone who disbelieves after this has indeed strayed off the right path. Because they violated their covenant, we put a curse on them, and We hardened their hearts. Consequently they distorted the scripture given to them, and disregard parts thereof. You will always see betrayal from them, except a few. You shall forgive and forget (the few), for God loves the compassionate. (5:12-13)
Jesus the son of Mary was sent to them with the purpose of demolishing this artificial Jewish religion. He was strengthened with the Holy Spirit and demonstrated miracles as signs that he was from God. He told the people he was enjoined to commit himself to undertaking the re-establishment of the laws of the Torah. It is self-evident that he spoke in his own language (which is rendered in Arabic in the Reading). What he said is found in the Reading as Sol-laa-ti-wa-zakaa-ti. The following statement was made while he was in the cradle:
Waja’al-lani mubarokah ainama kontu wa-ausorni bis-Sol-laa-ti wa-zakaa-ti ma-dumtu hiya (19:31)
And He makes me blessed wherever I go and He enjoined the obligations and purity upon me for as long as I live. (19:31)
When Jesus, son of Mary said wa-ausomi bis-Sol-laa-ti he did not mean I was enjoined with the ritual prayer but I was enjoined with the commitments to reform the Children of Israel, calling them to return to the original law given to Moses. He asked them to abolish the Jewish religion. That was his commitments. From the day he was born God gave him the knowledge of the scripture and the wisdom.
