11. Through the same chain of narrators as that of the previous Hadith the following is narrated from Ishaq ibn ‘Ammar who has said the following: “I once asked abu ‘Abd Allah , if I can have three shirts. He (the Imam) said, ‘It is not unlawful.’ I asked again until I reached ten shirts and he (the Imam) said, ‘Does exchanging give them more durability?’ I said, ‘It does, were I to wear one of them for a longer time, it would become less durable.’ He (the Imam) said, ‘It is not unlawful.’”
