Hadith 31-188

وَبِهذَا الإسناد قالَ: قالَ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَآلِهِ: يا عَلِيُّ إِنَّكَ أُعْطيتَ ثَلاثاً لَمْ يُعطَها أَحَدٌ مِن قَبْلِكَ، قُلْتُ: فِداكَ أَبي وَاُمِّي وَما أُعْطيتُ؟ قالَ: أُعْطيتَ صِهراً مِثلي وَأُعْطيتَ مِثلَ زَوجَتِك وَأُعْطيتَ مِثلَ وَلَدَيكَ الحَسَنِ وَالحُسَيْنِ.

According to the same documentation, God’s Prophet (S) said, “O Ali! You have been granted three things which no one has ever been granted before.” Ali (a.s.) said, “May my father and mother be your ransom! What have I been granted?” The Prophet (S) said, “You have been granted a father-in-law like me, a wife like (the Blessed Lady) Fatima, and sons like Al-Hassan and Al-Husayn.”
