277Abu Daawood, Nasaa'i & Tirmidhi, who declared it saheeh.
278Abu Daawood & Ibn Khuzaimah (1/87/2) with a saheeh sanad. `Abdul Haqq also declared it saheeh in his Ahkaam (56/2), as did Nawawi & Ibn Hajar. It was also transmitted via another route by `Abdur Razzaaq in his Musannaf (2/219), Abu Ya`laa in his Musnad (3/1253), Tabaraani in Mu`jam al-Kabeer (3/67/2) and Mu`jam al-Awsat (no. 4476 - my numbering) & Daaraqutni .
279Nasaa'i, Ahmad & Siraaj with a saheeh sanad.
280Ibn Khuzaimah, Baihaqi, Diyaa' in al-Mukhtaarah & `Abdul Ghani al-Maqdisi in his Sunan (243/1) with a saheeh isnaad; Ahmad, Tabaraani in Mu`jam al-Awsat (32/2), Baihaqi, Ibn al-Mulaqqin (29/1) and Haakim, who declared it saheeh and Dhahabi agreed. Its takhreej is given in Irwaa' al-Ghaleel under hadeeth no. 327.
281Muslim, Abu `Awaanah, Siraaj, Ibn Khuzaimah & Tabaraani.
*NB: The Ibaadiyyah have distorted this hadeeth: their scholar Rabee` has related it in his unreliable Musnad with a different wording to justify their view that raising the hands with takbeer invalidates the Prayer! That wording is false, as I have explained in ad-Da`eefah (6044).
282Haakim & Dhahabi declared it saheeh; it has already been given in full under the opening "Takbeer".
283 The first supplication is the fullest form of the du`aa' known as kaffaarah al-majlis (expiation of the gathering); "he who says it in a gathering of Remembrance (of Allaah), it will be like a seal to stamp it with, and he who says it in a gathering of vain talk, it will be an expiation for it" - authentically related by Haakim and Tabaraan. The second supplication is, of course, from the Sunnah of sending peace and mercy on the Messenger. These two supplications are thus the best way of implementing the following Islamic guideline: "No people sit in a gathering in which they do not mention Allaah, nor send prayers on the Prophet, without it being a source of regret for them; if Allaah wishes, He will punish them, or if He wishes, he will forgive them" - authentically related by Tirmidhi, Haakim & Ahmad. See Shaykh Albaani's Silsilah al-Ahaadeeth as-Saheehah (74-81) for details.
