The Lajnah ad-Da’imah stated:

With regard to specifying which night of Ramadan is Laylat-ul-Qadr; this requires specific evidence, however the odd-numbered nights during the last ten nights are more likely than others. The night of the twenty-seventh is the most likely to be Laylat-ul-Qadr based upon the Hadiths reported in this regard.

[Reference]

Also the Lajnah ad-Da’imah stated:

The practice of the Prophet (peace be upon him) during Ramadan was to offer many acts of worship like Salah (Prayer), recitation of the Qur’an, Sadaqah (voluntary charity), and to perform other good deeds. Over the first twenty nights of Ramadan, the Prophet (peace be upon him) might sleep or offer Optional Night Prayer. But when the last ten nights of Ramadan began, he (peace be upon him) would awaken his family, tie his lower garment (i.e., avoid sleeping with his wives), and devote himself entirely to worship at night… As to the celebration of the twenty-seventh night of Ramadan as Laylat-ul-Qadr, it is against the guidance of Allah’s Messenger (peace be upon him), for he did not celebrate Laylat-ul-Qadr. Hence celebrating it is considered as Bid`ah.

Question: 

Which hadith is being referred to that indicates that 27th is most likely laylatul Qadr?

Answer:

This is one Hadith:

إِنَّهَا لَيْلَةُ سَابِعَةٍ أَوْ تَاسِعَةٍ وَعِشْرِينَ، وَإِنَّ الْمَلَائِكَةَ تِلْكَ اللَّيْلَةَ فِي الْأَرْضِ أَكْثَرُ مِنْ عَدَدِ الْحَصَى

Verily, it is during the twenty-seventh or the twenty-ninth night. And verily, the angels who are on the earth during that night are more numerous than the number of pebbles

[Reported by Imam Ahmad and graded Hasan by al-Albani in Silsilatus-Saheeha no. 2205]

This is some of the evidences Shaikh al-Albani and others use as evidence to argue Laytul Qadr is mostly on the twenty seventh. Of course it is a difference of opinion as we know.
