1 – Reading Star Signs
Shaykh Salih Alaa ash – Shaykh -hafidhullaah- said :
‘Whoever reads the page which contains star signs and he knows the star sign of when he was born, or he knows that star sign which is significant for him, and he reads the comments mentioned in that star sign then it is as if he has asked a soothsayer/fortune teller. So his prayer would not be accepted for forty days.
If he attests to it and believes in that star sign then he has disbelieved in that which was revealed to Muhammad – sallAllaahu alayhi wa sallam- . . .’ (the Shaykh continues saying: ) ‘and if he brings home newspapers which contain these type of things then it is as if he brought a soothsayer / fortune teller into his house.’
[Tamheed Sharh Kitaab al Tawheed p. 349 ]
2 – Watching Magical Acrobatic Stunts & Circus Antics
Shaykh Salih Al-Fawzaan -hafidhullaah- said :
‘It is not permissible to use magic in the form of acrobatic stunts or circus antics or anything similar to that. Like the one who pulls a car with his hair, or a car is driven over him and does not harm him. . . . . all of this is magical imagery, so it is not allowed to perform it or to be happy with it, nor to attract your friends to do this in front of Muslims. Because it is clear evil, it is obligatory to reject and terminate it and to cleanse the Muslim lands of it . . . if those who go to see magic in the form of acrobatic stunts even though they are not pleased with going to see them, they have carried out something which is prohibited and they are sinful for it.
If they are pleased with this and they know that this is done by magic then they have fallen into disbelief because of it.’
[Daroos fee sharh Nawaqid al Islaam p. 152-156]
3 – Wearing an Engagement Ring
This enters under the saying of the Messenger – sallAllaahu alayhi wa sallam:
‘Indeed incantations, amulets and Tiwalah  (a form of magic) are Shirk.’
Collected by Ahmad and Abu Dawood.
Shaykh Muhammad Ibn Uthaymeen -rahimullaah – gave the example that an engagement ring is a Tiwalah and he explained:
‘If the people believe that it can benefit or harm, then with this intention it is from the minor Shirk, and even if this intention is not there – and this is highly unlikely that he does not have this intention – it is resemblance of the Christians since it is taken from them.’
[Al-Qawl al-Mufeed ala Kitaab al Tawheed 1 /228-229]
4 – Wearing Brass Bracelets to Battle Against Rheumatism
Shaykh AbdulAziz Ibn Baz – rahimullaah – said regarding these type of bracelets after having exhausted all the evidences:
‘The opinion which I hold in this issue is leaving these previously mentioned bracelets and not to use them; this is to block the path leading to Shirk, to terminate the aspect of any Fitnah with these bracelets and to incline to them, also that souls become attached to them.
Also, in having the incentive in turning the Muslim with his heart to Allaah -Subhanahu- and to have trust in Him, and reliance on Him sufficing with the means which are in accordance with the Sharia’ and their allowance is well known with committing Shirk.’
[Majmoo’ Fatawa ash-Shaykh Ibn Baaz vol.1 p.207]
All Praise belongs to Allaah, may His peace and blessings be upon our final Prophet Muhammad, his family, his companions and all those who follow his guidance.
