i think this is a belief of some shias...
OK I won't discuss that. I'll point out the passage I have pointed out before and discussed with Ansar al-Adl.
Sahih Bukhari Volume 8, Book 82, Number 817:
Narrated Ibn 'Abbas:
>deletions<
In the meantime, 'Umar sat on the pulpit and when the callmakers for the prayer had finished their call, 'Umar stood up, and having glorified and praised Allah as He deserved, he said, "Now then, I am going to tell you something which (Allah) has written for me to say. I do not know; perhaps it portends my death, so whoever understands and remembers it, must narrate it to the others wherever his mount takes him, but if somebody is afraid that he does not understand it, then it is unlawful for him to tell lies about me. Allah sent Muhammad with the Truth and revealed the Holy Book to him, and among what Allah revealed, was the Verse of the Rajam (the stoning of married person (male & female) who commits illegal sexual intercourse, and we did recite this Verse and understood and memorized it. Allah's Apostle did carry out the punishment of stoning and so did we after him.
I am afraid that after a long time has passed, somebody will say, 'By Allah, we do not find the Verse of the Rajam in Allah's Book,' and thus they will go astray by leaving an obligation which Allah has revealed. And the punishment of the Rajam is to be inflicted to any married person (male & female), who commits illegal sexual intercourse, if the required evidence is available or there is conception or confession. And then we used to recite among the Verses in Allah's Book: 'O people! Do not claim to be the offspring of other than your fathers, as it is disbelief (unthankfulness) on your part that you claim to be the offspring of other than your real father.' Then Allah's Apostle said, 'Do not praise me excessively as Jesus, son of Marry was praised, but call me Allah's Slave and His Apostles.'
So parts of it have been abrogated without their force being abrogated. I forget the technical legal term. Is this what was meant?
