Sayyiduna Abu Hurayrah (radiyallahu ‘anhu) reported that Rasulullah (sallallahu ‘alayhi wa sallam) said: “A person who is two faced cannot be trustworthy.” (Musnad Ahmad, vol. 2 pg. 289 and pg. 365, Al Adabul Mufrad, Hadith: 313. Also see: Fathul Bari, Hadith: 6058)

Receiving a prize in a lucky draw from a bank

Q: I am living in United Arab Emirates (Abu Dhabi). Here, there is a scheme available in the Banks by the name of "National Bond". In this scheme, I have to buy some bond with the minimum of 5000 Dirhams. This 5000 Dirhams will always be with the bank until I withdraw it. Every month the bank will have a lucky draw and the winning price will be 100 000 Dirhams or 1 Kg of gold, etc. If I withdraw the 5000 Dirhams then I no longer qualify to participate in the lucky draw. Is this halaal or haraam in Islam?

Women visiting the mubaarak grave of Rasulullah (sallallahu alaihi wasallam)

Q: I have a question regarding visiting the Raudhah (the blessed grave of Nabi (sallallahu alaihi wasallam)) as the workers here have created a doubt in my mind.

A staff member was explaining that when we (ladies) visit the Raudhah, our intention should purely be ibaadah in Riyaadhul Jannah and not to visit Rasulullah (sallallahu alaihi wasallam) as he disliked ladies visiting graveyards. Then she quoted an aayah or Hadith in Arabic and stated that Nabi (sallallahu alaihi wasallam) did not make an exception for ladies to visit his grave. So she mentioned that we should all rectify our intentions before going inside.

Is it correct for women to make the intention that they are visiting the grave of Rasulullah (sallallahu alaihi wasallam)?
