1. The hadith of the Pool
The Messenger of Allah (saw) said: As I was standing, there came a group of people whom I recognized, and a man stood between the group and myself, then said: "Let us go." I said, "Where to?" He said, "To Hell, by Allah!" I asked, "What have they done?" He answered, "They turned back after you had departed, and I expect only a few will reach salvation."
I shall arrive at the pool before you, and he who passes by me will drink, and whoever drinks from it will never feel thirsty. There will come to me people that I know and they know me, but we shall be separated, then I shall say, "My companions." An answer shall come, "You do not know what they did after you left." Then I shall say, "Away with those who changed after me."
When we look deeply at the various sayings that have been referred to by the Sunnis in their books, we will have no doubt that most of the Companions changed or even became apostates after the departure of the Messenger of Allah, except a few who were considered to be the minority. The above sayings could not be applied to the third type [of Companions], for they were the hypocrites, and the text states: I shall say, "My companions."
These sayings confirm and explain the Holy Qur'anic verses that we mentioned earlier on, which talked about their retreat and their apostasy and the terrible torture awaiting them.
2. The hadith of the Competition of the World
The Messenger of Allah (saw) said:
I lead you and am your witness, and by Allah I now look at my pool and have been given the keys to the treasures of the earth [for the earth's keys], and by Allah I am not worried that you become polythiest after me, but I am worried that you will compete for it"
