7. Ahmad ibn Idris has narrated from Muhammad ibn ‘Abd al-Jabbar from Safwan ibn Yahya from Yunus ibn Ya‘qub who has said the following: “I once sent (a letter) to abu ‘Abd Allah , to find out when Zakat becomes obligatory for the assets of my small brothers. He (the Imam) said, ‘

When Salah (prayer) becomes obligatory up on them, Zakat also become obligatory; however, in the case of those of them on whom Salah (prayer) is not obligatory but their asset is used in business, you must pay Zakat for such assets.’”
