Here are some of the authentic hadith about raisig hands in Salah:
Sahih Bukhari Volume 1, Book 12, Number 704: Narrated Abu Qilaba:
Isaw Malik bin Huwairith saying Takbir and raising both his hands (on
starting the prayers and raising his hands on bowing and also on
raising his head after bowing. Malik bin Huwairith said, “Allah’s
Apostle did the same.”
Volume 1, Book 12, Number 705:
Narrated ‘Abdullah bin ‘Umar:
I saw Allah’s Apostle opening the prayer with the Takbir and raising
his hands to the level of his shoulders at the time of saying the
Takbir, and on saying the Takbir for bowing he did the same; and when
he said, “Sami a-l-lahu Liman hamida “, he did the same and then said,
“Rabbana wa laka-l-hamd.” But he did not do the same on prostrating
and on lifting the head from it.”
Volume 1, Book 12, Number 706:
Narrated Nafi’:
Whenever Ibn ‘Umar started the prayer with Takbir, he used to raise
his hands: whenever he bowed, he used to raise his hands (before
bowing) and also used to raise his hands on saying, “Sami a-l-lahu
Liman hamida”, and he used to do the same on rising from the second
Rak’a (for the 3rd Rak’a). Ibn ‘Umar said: “The Prophet used to do the
same.”
Sahih Muslim
Book 004, Number 0759:
Ibn Umar reported that the Messenger of Allah (may peace be upon him),
when he stood up for prayer, used to raise his hands apposite the
shoulders and then recited takbir (Allah-o-Akbar), and when he was
about to bow he again did like it and when he raised himself from the
ruku’ (bowing posture) he again did like it, but he did not do it at
the time of raising his head from prostration.
Book 004, Number 0762:
Malik b. Huwairith reported: The Messenger of Allah (may peace be upon
him) raised his hands apposite his ears at the time of reciting the
takbir (i. e. at the time of beginning the prayer) and then again
raised his hands apposite the ears at the time of bowing and when he
lifted his head after bowing he said: Allah listened to him who
praised Him, and did like it (raised his hands up to the ears).
Muwatta Imam Malik
Book 3, Number 3.5.21:
Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah
that Abdullah ibn Umar used to say “Allah is greater” in the prayer
whenever he lowered himself and raised himself. Yahya related to me
from Malik from Nafi that Abdullah ibn Umar used to raise his hands to
the level of his shoulders when he began the prayer and when he raised
his head from the ruku he would raise them less than that.
Book 3, Number 3.5.17:
Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah
from Abdullah ibn Umar that the Messenger of Allah, may Allah bless
him and grant him peace, used to raise his hands to the level of his
shoulders when he began the prayer and when he raised his head from
the ruku he raised them in the same way, saying, “Allah hears whoever
praises him, our Lord and praise belongs to You.” He did not raise
them in the sujud.
Book 3, Number 3.5.18:
Yahya related to me from Malik from Ibn Shihab that AIi ibn Husayn ibn
Ali ibn Abi Talib said, “The Messenger of Allah, may Allah bless him
and grant him peace, used to say, ‘Allah is greater’ whenever he
lowered himself and raised himself, and he continued to pray like that
until he met Allah.”
Hadith:
Narrated by Wail Ibn Hujar (RA) that he saw at the beginning of salah
prophet (SAW) used to start his salah by saying Allahu Akbar and raise
his hands up to the ears. (According to Hammam) (SahihMuslim1/401)
Regarding your point of facing palms to direction of Qibla, i could not find any evidence of it. And i heard from different scholars that facing hands towards qibla is not necessary, just the hands should be upto the ears, they can or cannot face qibla.
