Musnad Ahmad 4290
Musnad of Abdullah bin Mas'ood
It was narrated from ‘Abdullah from the Prophet (ﷺ) that He said: I used to forbid you to visit the graves, but now you may visit them. And I used to forbid you to keep the sacrificial meat for more than three days, but now you may keep it. And I used to forbid you (to use vessels) to soak dates in, but now you may use them, but avoid everything that intoxicates.
