َدَ عَنِ الْحُسَيْنِ بْنِ ٠َالِكٍ قَالَ كَتَبْتُ إِلَيْهِ رَجُلٌ ٠َاتَ وَجَعَلَ كُلَّ شَيْ‏ءٍ لَهُ فِي حَيَاتِهِ لَكَ وَلَ٠ْ يَكُنْ لَهُ وَلَدٌ ثُ٠َّ إِنَّهُ أَصَابَ بَعْدَ ذَلِكَ وَلَداً وَ٠َالِهِ ثَلاثَةُ آلافِ دِرْهَ٠ٍ وَقَدْ بَعَثْتُ إِلَيْكَ بِأَلْفِ دِرْهَ٠ٍ فَإِنْ رَأَيْتَ جَعَلَنِيَ اللهُ فِدَاكَ أَنْ تُعْلِ٠َنِي فِيهِ رَأْيَكَ لأعْ٠َلَ بِهِ فَكَتَبَ أَطْلِقْ لَهُ٠12.

It is narrated from the narrator of the previous Hadith from Muhammad ibn Ahmad from al-Husayn ibn Malik who has narrated the following: “I once wrote to him (the Imam) (a.s.), ‘A man has died who in his lifetime had made everything that he had for you and he did not have any children, thereafter a child was born to him and his assets are three thousand dirham. He has sent to you one thousand dirham.

I like to know your decision in the matter so I can follow.’ He (the Imam) (a.s.), wrote the answer that said, ‘I leave it for them.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (23/97))
