In previous Ans u advised me to be careful in areas of ilm that the duat whom i followed deviated in. So for eg if they hold wrong political views or r like ikhwani& some of their fatawa r wrong eg. Hijab, etc., can i follow fatwa of other areas(eg.wudhu)or must I doubt everything of the past 16 yrs

In these areas, you should of course turn away from them. Do not doubt them, just straight out reject what they said unless you confirm it from an Imam like Ibn Baz, Ibn al-Uthaymeen, al-Albani, al-Fawzan, Salih al-Luhaydan, and so on. These are areas where they have violated principles in terms of: 1. Politics 2. Obedience to the Muslim rulers Etc
