1. Al-Husayn ibn Muhammad and Muhammad ibn Yahya have all narrated from Ali ibn Muhammad ibn Sa’d from Muhammad ibn Muslim from abu Salmah from Muhammad ibn Sa’id ibn Ghazwan from ibn abu Najran from Muhammad ibn Sinan from abu Khadijah who has said the following: “Once I went to see abu al-Hassan (a.s.) and he said to me, ‘Allah, the Most Blessed, the Most High, supports a believer with a spirit from His side who attends him in all times that he performs a good deed and observes piety. The spirit remains absent in all times that he commits sins and transgresses. The spirit vibrates with joy when he does a good deed and turns into a despicable thing and lowly to earth when he commits a sin. O servants of Allah, be committed to benefit from the favors of Allah to correct and reform yourselves; it (commitment) will increase your certainty and you earn fine and valuable things. May Allah grant favors to those who think of doing good and perform it or think of committing something bad, but refrain and desist.’ The Imam then said, ‘We support and strengthen the spirit by means of obeying Allah and working for Him.’”
