Hadith record

2. A number of our people have narrated from Sahl ibn Ziyad from Ja’far ibn Muhammad al-Ash’ari from ibn al-Qaddah from Abu ‘Abdillah (a.s.) who has said the following: “Amir al-Mu’minin, Ali ibn abu Talib (a.s.) has said, ‘Allah, the Most Majestic, the Most Holy, does not accept the prayer from a thoughtless heart. Ali (a.s.) would say, ‘Whenever any of you may pray for a dead person, he must not do it frivolously but must strive to be serious in his prayer.’”
