Arabic hadith text
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، أَنَّ سَعِيدَ بْنَ الْمُسَيَّبِ، كَانَ يَقُولُ إِنَّ الرَّجُلَ لَيُرْفَعُ بِدُعَاءِ وَلَدِهِ مِنْ بَعْدِهِ وَقَالَ بِيَدَيْهِ نَحْوَ السَّمَاءِ فَرَفَعَهُمَا ‏.‏
Translation

Yahya related to me from Malik from Yahya ibn Said that Said ibnal-Musayyab used to say, "A man is raised by the dua of his son afterhis death." He spoke with his hands turned upwards, and then liftedthem up.
