Myth of Quran's lost verse about stoning answered

Christian missionaries and other anti-Islamic polemics try to question the authority of the Quran by misinterpreting the following Hadith about the punishment of stoning.
----------------"In the meantime, 'Umar sat on the pulpit and when the call makers 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.

Exposing the lie of Quran's lost verse about breastfeeding

There is a Hadith reported from Sayyidah Aisha (RA) which gives a notion as if some verse about five suckling was revealed and was recited till the death of the Holy Prophet (PBUH) which is obviously not found in any of the Quranic manuscripts known in history. The tradition goes as:

عَنْ عَائِشَةَ أَنَّهَا قَالَتْ كَانَ فِيمَا أُنْزِلَ مِنْ الْقُرْآنِ عَشْرُ رَضَعَاتٍ مَعْلُومَاتٍ يُحَرِّمْنَ ثُمَّ نُسِخْنَ بِخَمْسٍ مَعْلُومَاتٍ فَتُوُفِّيَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُنَّ فِيمَا يُقْرَأُ مِنْ الْقُرْآنِ

---'A'isha (Allah be pleased with, her) reported that it had been revealed in the Holy Qur'an that ten clear sucklings make the marriage unlawful, then it was abrogated (and substituted) by five sucklings and Allah's Apostle (may peace be upon him) died and it was before that time (found) in the Holy Qur'an (and recited by the Muslims). (Sahih Muslim, Hadith 2634) --
