Are the conditions of Hady the same as those of an Ud-hiyah with regard to age and faults?

Q: I hope Your Eminence to provide me with Fatwas on the following issues:1: What is the meaning of Allah's (Exalted be He) Saying: ...he must slaughter a Hady such as he can afford ?2- Are the conditions of Hady (sacrificial animal offered by pilgrims) the same as those of an Ud-hiyah (sacrificial animal offered by non-pilgrims) with regard to age and faults? 3- Is it permissible to slaughter the Ud-hiyah and Hady after the first day of `Eid-ul-Adha (the Festival of the Sacrifice)? 4- Is it permissible to slaughter for a vow at night or not? If it is not permissible to do so, what is the evidence for that?5- When does the time of Takbir (saying: "Allahu Akbar [Allah is the Greatest]") start in the first ten days of Dhul-Hajjah and when does it end?6- A man said: "If such and such happens, a sacrifice will be incumbent on me." The question is: Is the ruling of the sacrifice of `Eid the same as that of a vow? Is it permissible for its owner to eat from it or not?I ask Allah the All-Sublime and All-Powerful to guide us to what he loves and to benefit (Part No. 10; Page No. 395) Muslims with your knowledge!

A: Firstly: As for Allah's (Exalted be He) Saying: ...he must slaughter a Hady such as he can afford This means whatever is available of livestock, which includes camels, cows and sheep. The least of the Hady is a sheep meeting the same conditions for an Ud-hiyah (sacrificial animal offered by non-pilgrims). Secondly: Yes, this is a condition. Thirdly: It is better and worthier to slaughter the Hady and Ud-hiyah in the daytime and if it is sacrificed during the nights of the Days of Tashriq (11th, 12th and 13th of Dhul-Hijjah), it will be valid. Fourthly: The unrestricted Takbir (saying: "Allahu Akbar [Allah is the Greatest]") starts from the Fajr (Dawn) of the first of the ten days of Dhul-Hajjah while the restricted Takbir is said after Prayer starts from the Fajr of the day of `Arafah until the `Asr (Afternoon) Prayer of the last day of the Days of Tashriq (11th, 12th and 13th of Dhul-Hijjah). Fifthly: If the condition happened, it is obligatory to fulfill the vow of `Eid [namely the Festival of the Sacrifice] because it is a vow in the meaning. If he did not intend certain people, he should distribute it among the poor.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
