٣ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ رَجُلٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ (عَلَيْهِ الْسَّلام) قَالَ مَنْ أَرَادَ أَنْ يُحْبَلَ لَهُ فَلْيُصَلِّ رَكْعَتَيْنِ بَعْدَ الْجُمُعَةِ يُطِيلُ فِيهِمَا الرُّكُوعَ وَالسُّجُودَ ثُمَّ يَقُولُ اللهمَّ إِنِّي أَسْأَلُكَ بِمَا سَأَلَكَ بِهِ زَكَرِيَّا إِذْ قَالَ رَبِّ لاَ تَذَرْنِي فَرْداً وَأَنْتَ خَيْرُ الْوَارِثِينَ اللهمَّ هَبْ لِي ذُرِّيَّةً طَيِّبَةً إِنَّكَ سَمِيعُ الدُّعَاءِ اللهمَّ بِاسْمِكَ اسْتَحْلَلْتُهَا وَفِي أَمَانَتِكَ أَخَذْتُهَا فَإِنْ قَضَيْتَ فِي رَحِمِهَا وَلَداً فَاجْعَلْهُ غُلاَماً وَلاَ تَجْعَلْ لِلشَّيْطَانِ فِيهِ نَصِيباً وَلاَ شِرْكاً. 
3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from a man from Muhammad ibn Muslim who has said the following: “Abu Ja’far , has said, ‘If one wants that his wife become pregnant, he should perform two Rak‘at Salah (prayer) after Friday Salah (prayer). In this Salah (prayer) he should prolong his Ruku‘ and sajdah and then say, “O Allah, I ask You just what Zachariah asked You for, O my Lord, (rabbi) do not leave me lonely (childless) while You are the best heir. O Allah, grant me virtuous offspring. You hear (all prayers and appeals). O Allah through Your name she has become lawful for me and as Your trust, I have taken her as my wife. If You will decree a child in her womb, please make the child to be a righteous (honorable one, an intelligent) son and do not allow Satan to have a part or share in him.’”
