(Fatwa: 1484/1163/D=1431)
The ruling of talaq will not be applicable even for Shabana merely by having thought in heart. Yes, if you have uttered the sentence “Shadi Karon to talaq” (if I marry then talaq) verbally, so in this case, since you intended to avoid nikah with Shabana; hence by doing nikah with Shabana talaq shall take place. And if you marry a woman other than Shabana, then no talaq shall take place.
Allah knows Best!
