Jabir ibn Abdullah (may Allah be pleased with him) reported that the Prophet (pbuh) said:
Whoever has three daughters and he accommodates them, show mercy toward them, and supports them, Paradise is definitely guaranteed for him.
Thus, someone asked the Prophet, what if they are two daughters only
He replied, “[He gets that reward,] even if they are [only] two.“
Some of those present believed that had the Prophet been asked about only one daughter, he would have answered that the reward was applicable too. (Authenticated by Al-Albani)
