Final answer:
The correct reference for the timeline is to the Muslim religious group, indicated by their belief that they worship the same God as Jewish people and Christians, and the historical context of the Delhi Sultanate rulers following Islam.
Step-by-step explanation:
The timeline in question seems to reference events related to the Muslim religious group. In response to question 2 on Muslim belief, the accurate statement is c. Muslims worship the same God as Jewish people and Christians. This indicates the monotheistic tradition shared among these Abrahamic faiths. The rulers of the Delhi Sultanate mentioned in question 3 followed Islam.
As for the sacred texts and beliefs, while all three of the Abrahamic faiths share many historical religious stories, the sacred text for Christians is the Bible. They diverge in their beliefs about the messiah; Christians believe Jesus was the son of God whereas Jews and Muslims see the prophecy about the messiah's coming as not yet fulfilled. For Jewish people, the sacred text is the Torah, and in 1492, the Jews and Muslims were forced to either convert or leave Spain. The Five Pillars are indeed the principles of religious duties in Islam, reflecting how faith integrates into daily life.
