1. A number of our people have narrated from Ahmad ibn Muhammad from Muhammad ibn Isma’il from ibn Bazi‘ from abu Isma’il al- Sarraj who has said the following: “Abu ’Abd Allah (a.s.), has said that a son whom one sends (to the next life) is better than seventy sons who survive after one’s death, who have mounted their horses and are ready to march for the cause of Allah.”

2. Abū ‘Alī al-Ash‘arī narrated from Muḥammad ibn Sālim, from Aḥmad ibn al-Naḍr, from ‘Amrū ibn Shimr, from Jābir, who reported from Abū Ja‘far (as), who said: "The Messenger of Allah (sw) entered upon Khadījah when her son Qāsim had died, and she was weeping. He asked her, 'What makes you weep?' She replied, 'My milk flowed, and so I wept.' He said, 'O Khadījah, would you not be pleased if on the Day of Resurrection, you come to the gate of Paradise and Qāsim is standing there, taking your hand and leading you into Paradise, placing you in its best place? This is for every believer. Verily, Allah the Almighty and Glorious is too wise and too generous to take away the fruit of a believer's heart and then punish them afterward, ever.'"

3. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa and a number of our people from Sahl ibn Ziyad all from ibn Mehran who has said the following: “A man once wrote to abu Ja‘far, the second (a.s.), complaining due to his suffering from the death of his sons and the intensity of his grief. The Imam wrote to him, ‘Do you know that Allah, the Most Majestic, the Most Glorious, chooses from the property and sons of the believing people the most valuable items so He will reward him in the same way (with most valuable reward)?”’

4. Ali ibn Ibrahim has narrated from his father, from al-Nawfaliy from al-Sakuniy who has said the following: “Abu ‘Abd Allah (a.s.), has said that the Messenger of Allah has said, ‘When a son of a believing person dies - Allah knows what the servant (of Allah) may say - Allah, the Most Holy, the Most High, says to His angels, “Have you taken the soul of the son of My servant out of his body?” They reply, “Yes, O Lord, we have done so.” He then asks, “What did My servant say?” They say, “He praised You and said, ‘We are for Allah and to Him we return.’” Allah, the Most Holy, the Most High, then says, “So you took away the fruit of his heart and the delight of his eyes but he praised Me and spoke of his return to Me. (For his reward) build a house for him in paradise and call it the house of al-Hamd (praising Allah).””’
