A short talk by Shaykh Abdul Kerim advising mureeds on the Naqshbandi path to avoid eating out at restaurants:
Some points made:
1) The amount of money it costs to feed one person at a restaurant could be used to feed ten people if you went and bought from a supermarket.
2) Traveling is no excuse.
3) Especially in this [western] country, the food at restaurants is cooked and prepared without the name of Allah (swt), and instead, with curses.
4) It would be a greater blessing to buy the food and prepare it yourselves and to then sit and eat.
5) For those claiming to follow Shaykh Mawlana, that’s also what he does – to prepare food ahead of time before traveling or to stop and buy from a supermarket.
