A murid said to his pir: ‘What am I to do? I am troubled by the people, many of whom pay me visits. By their coming and going they encroach upon my precious time.’ He replied: ‘Lend something to every one of them who is poor and ask something from every one who is rich and they will come round thee no more.’

If a mendicant were the leader of the army of Islam,
The infidels would for fear of his importunity run as far as China.
