"The Messenger of Allah ﷺ passed by, so my mother, Umm Sulaim, heard his voice and said: 'May my father and mother be ransomed for you, O Messenger of Allah. This is Unais.' So the Messenger of Allah ﷺ supplicated for me with three supplications, and I have seem two of them in the world, and I hope for the third in the Hereafter."  

مَرَّ رَسُولُ اللَّهِ ﷺ فَسَمِعَتْ أُمِّي أُمُّ سُلَيْمٍ صَوْتَهُ فَقَالَتْ بِأَبِي أَنْتَ وَأُمِّي يَا رَسُولَ اللَّهِ أُنَيْسٌ قَالَ فَدَعَا لِي رَسُولُ اللَّهِ ﷺ ثَلاَثَ دَعَوَاتٍ قَدْ رَأَيْتُ مِنْهُنَّ اثْنَيْنِ فِي الدُّنْيَا وَأَنَا أَرْجُو الثَّالِثَةَ فِي الآخِرَةِ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ وَقَدْ رُوِيَ هَذَا الْحَدِيثُ مِنْ غَيْرِ وَجْهٍ عَنْ أَنَسٍ عَنِ النَّبِيِّ ﷺ  

Messenger of Allah ﷺ passed (by our house) that my mother Umm Sulaim listened to his voice and said: Messenger of Allah, let my father and mother be sacrificed for thee, here is Unais (and requested him to invoke blessings upon me). So Messenger of Allah ﷺ invoked three blessings upon me. I have seen (the results) of the two in this very world (in regard to wealth and progeny) and I hope to see (the result) of the third one in the Hereafter. (Using translation from Muslim 2481c)  

مَرَّ رَسُولُ اللهِ ﷺ فَسَمِعَتْ أُمُّ سُلَيْمٍ صَوْتَهُ فَقَالَتْ بِأَبِي وَأُمِّي يَا رَسُولَ اللهِ أُنَيْسٌ فَدَعَا لِي رَسُولُ اللهِ ﷺ ثَلَاثَ دَعَوَاتٍ قَدْ رَأَيْتُ مِنْهَا اثْنَتَيْنِ وَأَنَا أَرْجُو الثَّالِثَةَ فِي الْآخِرَةِ  

"جَاءَتْ (* * *) أُمُّ سُلَيْم إِلَى رَسُولِ الله ﷺ فَقَالَتْ: يَا رَسُولَ الله! بِأَبِى (* * * *) أنْتَ وَأمِّى أُنَيْس لَوْ دَعَوْتَ الله فَدَعَا لِى بِثَلاثِ دَعَوَات قَدْ رَأَيْتُ الثِّنْتَيْنِ، وَأنَا أَرْجُو الثَالِثَةَ".
