The Minimum Requirement for Talaaq

1. Once the husband says verbally, “I have given my wife talaaq,” and he said it loud enough for him to hear it, the talaaq comes into effect.
2. It does not matter whether he said it in that manner in front of someone or whilst being alone.
3. Similarly, the wife hearing it or not hearing it is not a condition.
4. In all the cases mentioned the talaaq comes into effect.
