[Centurnion]

Assalaamu Alaikum wa rahmatullah,

I am in a dilemma.

Mu'tamad view of the madhab (as per my limited knowledge)
So, let's say I pay my Zakah on 31 December every year.

31 December 2010 - Cash Savings - £100,000
31 December 2011 - Cash Savings - £50,000
Net Income earned over 2011 - £75,000 (consists of wages and salaries less deductions)

So according to the madhab, I have only maintained £50,000 for the full year*. So £50,000 is the zakatable amount.
Total Zakah = 2.5% = £1,250

NB: *I am aware that the lunar year is technically 11 days shorter but this is a hypothetical situation.

View of Shaykh Yusuf Qaradawi (hafidhahullah)
31 December 2010 - Cash Savings - £100,000
31 December 2011 - Cash Savings - £50,000
Net Income earned over 2011 - £75,000 (consists of wages and salaries less deductions)

Zakatable savings = £50,000 as before. 2.5% = £1,250
Zakatable earnings = £75,000. 2.5% = £1,875
Total zakah = £3,125

NB: Again hypothetical situation. Don't earn anywhere close to £75k! Not yet haha!

Question
I have read through the relevant extract in Shaykh Qaradawi's Fiqh us-Zakah and I attach it for reference. If I am honest, I find his arguments very compelling and convincing.

So my question - would it be permissible to break away from the (shafi'i) madhab and follow the opinion of Shaykh Qaradawi in this case? Also, if one finds an opinion stronger, would it still be permissible to follow the other (relied upon) opinion? Sorry these are more usooli questions rather than zakah questions!
