Is it permissible for one who has performed the 'Umrah of tamattu' to perform the sa'y of Hajj on the eighth day before going to Mina? And what is the ruling on one who does so?

Al-Halabi: And likewise the hadith ?

The Shaykh : This is known to us to be weak ever since we became familiar with its chain of narration. Perhaps it is fitting, on this occasion, to remind you that the full text of this hadith is We reject the text of this hadith, in addition to its being weakened due to its chain of narration, for this reason: because a believer, no matter how bad his deeds and actions may be, and no matter how far he is from the mindfulness of Allah (Blessed and Exalted is He), is as he (peace and blessings be upon him) said in a hadith in al-Bazzar: Therefore, it is not correct to group him, or to say that the one who abandons prayer, if he is a believer in Allah and His Messenger, will be gathered with Qarun, Pharaoh, and Haman, who claimed lordship and divinity. Every student of knowledge must know that it is established in the two Sahihs in the hadith of intercession: What is the description of those in whose behalf the righteous believers, who were the first to enter Paradise, interceded? They used to pray, fast, and perform Hajj, but they committed some sins and transgressions, so they entered the Fire because of them. Then the intercession of the interceders came and brought them out. فيقولون يا ربّ لقد أخرجنا من أمرتنا فيقول الرّب تبارك و تعالى فأخرجوا من النار من كان في قلبه مثقال دينار من الإيمان فيعودون ويخرجون من كان في قلبه وزن دينار من إيمان فيخرجون خلقا كثيرا So they say: "Our Lord, we have brought out those whom You commanded." So the Lord (Blessed and Exalted is He) says: "Bring out of the Fire whoever has in his heart the weight of a dinar of faith." So they return and bring out whoever has in his heart the weight of a dinar of faith, and they bring out a great number of people. Do you see? Are these among the praying people? They are not among the praying people, because the praying people were brought out in the first group. ثمّ بعد أن يخرجوا خلقا كثيرا يقولون " يا ربّنا قد أخرجنا من أمرتنا " فيقول أخرجوا من النّار من كان في قلبه وزن نصف دينار من الإيمان فيخرجون خلقا كثيرا Then, after they bring out a great number of people, they say: "Our Lord, we have brought out those whom You commanded." So He says: "Bring out of the Fire whoever has in his heart the weight of half a dinar of faith." So they bring out a great number of people. And so on, until the end of the hadith, where it says: فيقول الرّب تبارك وتعالى شفعت الملائكة و شفعت الأنبياء و شفع المؤمنون و لم يبق إلاّ شفاعة أرحم الرّاحمين فيأمر بإخراج من لم يعمل خيرا قطّ , من لم يعمل خيرا قطّ So the Lord (Blessed and Exalted is He) says: "The angels have interceded, and the prophets have interceded, and the believers have interceded, and nothing remains except the intercession of the Most Merciful of the merciful." So He commands the bringing out of whoever has never done any good, whoever has never done any good. meaning he did not pray, he did not give zakah, and only the weight of an atom of faith was in his heart. This hadith is in the two Sahihs, and it is an explicit text that there are two things with us: first, it is not permissible to equate a Muslim who abandons prayer with Qarun, Haman, and Pharaoh; and second, it is not permissible to declare a disbeliever the one who abandons prayer if he believes in it and does not deny its legality, but rather abandoned it out of laziness. This is an explicit text that should resolve the disagreement that has taken root today among many people, especially since the majority of scholars do not consider the one who abandons prayer out of laziness to be a disbeliever. And praise be to Allah, Lord of the worlds.
