What is the meaning of the Tashahhud, why was Fatimah called Az-Zahra, and must a woman wear a hijab when reciting the Quran?

"Al-Tahiyyat (greetings) are sovereignty, or peace, or greatness, or permanence, and their meaning is that these attributes are due to Allah alone. Al-Salawat (prayers) can mean the customary prayers offered to Allah, or the sincerity of our prayers to Him, or mercy, and that Allah is the Bestower of it. Al-Tayyibat (good things) have been interpreted as good words, and more generally, they include good words, deeds, and attributes that are free from blemish. Fatimah, may Allah be pleased with her, was given the title Al-Zahra. The reason for this naming is not explicitly mentioned, but 'Zahra' means whiteness and beauty. As for a woman reciting the Quran without a head covering, the ruling on this has been previously clarified."
