Answer
(Fatwa: 2221/1497/H=1431)
One talaq took place on asking for food (according to the condition). Now the ruling is that you can take her back in your nikah before the iddah period is over, provided you have given no talaq before or after this conditional talaq. If you have given any talaq, give its detail and submit the question again. And if the iddah was over and you did not take her back in your nikah, then in the case of one talaq you can perform new nikah with the consent of your divorced wife. This is mentioned in Fatawa Shami and Fatawa Al-Hindiyah etc.
