7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ahmad ibn Muhammad from ibn abu Nasr who has said the following
“I once asked abu al-Hassan (a.s.), about cutting down a lotus tree. He (the Imam) said, ‘One of your people asked me about it and I wrote to him that abu al-Hassan (a.s.), once cut down a lotus tree and planted in its place grape-vines.’”
