Going to peoples houses for khatam

Q: People call me to there house for khatam. They say sit in the middle and they tell me we have done e.g. 10 katams of Qur'an, many thousands ayaat-e-karima and I do dua for the diseased then we eat. Is it permissible for me to eat? They also give money at the end. What is the Shari'ee hukm with reference?

Congregational Dua

Q: One person who has ta'lluq with the salafees told me that making dua with jamaat after salaah is not established. Therefore we shouldn't make it in group. Rather each one should make his dua separately.

Encouraging the musallees to do what is right

Q: I lead the prayers in the Masjid. Many people stand with there children in the first saff. The children are under 9. When I tell them make the children stand at the back they do not listen. What is the Shar'iee hukm? Is it makruh for them to stand in first saff? Are they allowed to stand in second saff or they should stand in last row on the left side? Please give me reference from Hadith so I could explain to them and also if they do not listen how should I advise them?

Zakaat on property

Q:

  1. Is Zakat due on the current market value of the land or the original value at which it was bought given that the land is still in my possesion? Also the intention of buying this land is to build a house for personal use.
  2. In order to avoid Riba (interest) to buy a house without mortgage, I am intending to buy land(s) such that after few years I will buy a house for my own personal use after selling 1 or more lands. Is Zakat still due on this land(s)? If yes then on principal amount or current market value?
