Whenever you prepare a broth, add water to it, and have in your mind the members of the household of your neighbours and then give them out of this with courtesy. (Using translation from Muslim 2625c)   

«إِذَا طَبَخْتَ مَرَقَةً فَأَكْثِرْ مَاءَهَا ثُمَّ انْظُرْ أَهْلَ بَيْتٍ مِنْ جِِيرَانِكََ فَاغْرِفْ لَهُمْ مِنْهَا»
