The Prophet (Sallallaho alaihe 'wasallam) accepts a woman's invitation:

The Prophet (Sallallaho alaihe wasallam) was once returning from a funeral, when a woman invited him to partake  of some food at her· house. 

He went in with some of his Sahabah.WheIi the food was served, it was noticed Hiat the Prophet (Sallallaho alaihe wasallam) was trying to chew a morsel, but it 'would simply not go down his throat.

He said:

"It seems that the animal has been slaughtered without the permission of its owner."

'The woman said:

 "0h, Prophet of Allah! I had asked a man to purchase a goat for me from the market.

 but he could not obtain one.

 My neighbour also had recently purchased a goat.

So I sent the man thither with some money to buy the same from him:

 My neighbour was out and his wife made the goat to my man."

The Prophet (Sallallaho alaihe wasallam) directep her to go and serve the meat to the captives.

It has been noted of pious and saintly Muslims that food obtained from doubtful sources would simply not go down their throats.

 So this is not such a surprising thing in Pieiy and Scrupulousness the case of the Prophet (Sallallaho alaiheowasa11am), who is the fountain head of all piety.
