Sometimes the person (s) travelling with one might prove satanic traps. He might be foul mouthed, backbiter or a person of poor intellect. Such a companion should be avoided.

Two companions, particularly when they are women, whose will is generally weak, have tendency to be ensnared by Satan. When they start gossiping, other's matters come up for discussion. As time passes, they shift from innocuous talk to backbiting, insinuations, scandals, mockery and many such taboo things.

The trap of Iblees is such that in the beginning people talk about eac other's health, exchange humor and narrate interesting anecdotes. But then Satan misguides them to fall into his trap and start discussing taboo things.

You must have witnessed that when two persons get together, their talk initially had no element of fault. But in about an hour's time there will be an element of lies in their conversation that might push them into the morass of Hell. Emerging out of the morass will be a Herculean task. As a follow up to the conversation, even if they go to a mosque, you should not think that they are God fearing persons because Satan continues to be with them.
