Answer:
Respect for the caliphs were declining.
Lack of unity among people.
Explanation:
After the fragmentation of the Abbasid caliphate, different groups were formed and some groups were led by non-Arabian Muslims. Respect for the caliphs were declining due to this fragmentation which leads to the end of Abbasids and the rise of the Buyids.

Sufism and good behaviour of Muslim emperors are the main factors that contribute to the spread of Islam within India.
