Answer:
The Islamic construction that is a tomb is the Taj Mahal.
Explanation:
The Taj Mahal is mausoleum in the Indian city of Agra. The construction was order in 1632 by Shah Jahan, a Mughal emperor that ruled Agra from 1628 to 1658, in memory of his deceased wife, Mumtaz Mahal, who died giving birth to one of their many children. Now days it serves as Jahan's tomb as well.
Although it was commissioned in 1632, it was completed on 1643 and some works continued for another 10 years.
It is a beautiful architectonic piece, placed in the center of the Taj Mahal complex. It is a symmetrical white marble construction standing on a pedestal with an arch-shaped doorway and a large marvelous onion dome at the top.
The building mixes both traditions, Persian and Mughal and does hold a Mosque as well as a guest house.
On the main gate there is an inscription reading "O Soul, thou art at rest. Return to the Lord at peace with Him, and He at peace with you." all the calligraphy and decorations are stunningly beautiful and delicate mirroring the admiration and love that Shah Jahan felt for his wife. It is a symbol of love.
The garden has large pathways and flowerbeds that lead to the construction. Prior to the tomb there is a marble water tank which reflects the building. Every detail was carefully thought and full of symbolism.
It was said that the emperor wanted to build a Black Taj Mahal across the current one to officiate as his tomb but never got the opportunity to build it.
Muslim tradition does not allow excessive decorations on graves; this is why the real tombs of Mumtaz and Shah Jahan are actually placed on a lower, more simpler crypt.
It is one of UNESCO's' World Heritage Site since 1983 and its worldwide admired and considered to be one India's symbols.
