what happend the friendship of Dr Aziz and Mr fielding?

Dr. Aziz

A Moslem doctor living in Chandrapore at the beginning of the novel, he is a widower with three children who meets Mrs. Moore, an elderly English widow who has three children herself and becomes friends with her. Although he is generous and loving toward his English friends, including Mrs. Moore and Cyril Fielding, after Adela Quested accuses him of assault he becomes bitter, vindictive and notoriously anti-British. A primary concern of A Passage to India is the shift in Dr. Aziz's views of the British from accommodating and even a bit submissive to an aggressively anti-colonial stance.

Cyril Fielding

The schoolmaster of Government College, Fielding stands alone among the British officials in India, for he is one of the few to treat the Indians with a sense of decency and respect. Fielding is an individualist who has no great allegiance to any particular group, but rather to his core set of liberal values and sense of justice. This quality allows Fielding to break with the English who support Adela Quested's charges against Aziz and side with the Indians in support of him. However, the events surrounding Aziz's trial cause Fielding to become disenchanted with India, despite his affection for the nation, and motivate him to leave India and return to resume a different post.
