Al-Mahdi

"Nobody seeks my help with a petition or offers an excuse that is more pressing than he, reminding me of a favor I did him so that it would be followed by its sister (i.e, one like it) and so good would be done to its asker because withholding of later things removes gratitude for earlier ones."

"In the year 159 (AD 776) Al Mahdî sent an army by sea under ‘Abdul Malik bin Shahãbu’l Musamma’î to India… They proceeded on their way and at length disembarked at Barada. When they reached the place they laid siege to it… The town was reduced to extremities, and God prevailed over it in the same year. The people were forbidden to worship the Budd, which the Muhammadans burned."
