Sub-h'aanallaahi wal h'amdu lillaahi wa laa ilaaha illallaahu akbar

Imam Jafar Sadiq (a.s) says that the Messenger of Allah (saw) turned towards his companions and said, "Pick up the sheild of Allah." The companions asked, "There is no enemy; why should we pick up the shield?" The Holt Prophet (saw) said, "Pick it up for combating the Hell and recite Sub-h'aanallaahi wal h'amdu lillaahi wa laa ilaaha illallaahu akbar."

Imam Jafar Sadiq (a.s) says that the Messenger of Allah (saw) said, "Recite Sub-h'aanallaahi wal h'amdu lillaahi wa laa ilaaha illallaahu akbar often because this statement will come to you surrounded by angels and will be included among your good deeds."

Imam Muhammad Baqir (a.s) says, "One who says Sub-h'aanallaah Allah will plant a tree for him in Paradise. One who says Alh'amdulillaah then too a tree will be planted for him in Paradise. Similarly, one who says laa ilaaha illallaah then also Allah will plant a tree for him in Paradise. Allah will also plant a tree for one who recites Allah akbar. A man of quraish said, "O Messenger of Allah (saw) then there would be many trees in the Paradise for us?" "Yes but br careful that you do not send fire or they all would get burnt up. That is why the Almighty Allah said: 'O you who believe! Obey Allah and obey the Apostle and do not make your deeds of no effect.'"

Imam Jafar Sadiq (a.s) says that one day the Messenger of Allah (saw) asked his companions,  "Do you know that if your clothes and utensils are gathered in one place and kept one above another they reach the sky?" They replied, "No!" The Holy Prophet (saw) said, "Should I tell you about a thing whose roots are in the earth and branches above the sky?" Everyone replied,
Indeed we want to know it." The Holy Prophet (saw) said, "One who recites  Sub-h'aanallaahi wal h'amdu lillaahi wa laa ilaaha illallaahu akbar (the roots of this statement are in the earth and its branches are above the sky) thirty times after each obligatory prayers the above statement will safeguard him from being crushed under a wall, drowning, falling in well, falling prey to wild animals, death due to accidents and from dangerous things falling from skies. This statement will remain as permanent good deeds for him."
