Some of the deeds that will cause a person to be in hell temporarily.
1⃣ Lying about [falsely attributing words to] the Messenger of Allah (Salallaahu Alaihi Wasalaam )
Ibn al-Ithir included in his famous book, Jaami’ al-Usool a chapter in which he quoted many hadith that warn against lying about the Prophet (Salallaahu Alaihi Wasalaam ). These include the report by al-Bukhaari, Muslim and at-Tirmidhi from ‘Ali ibn Abi Taalib who said: “The Messenger of Allah (Salallaahu Alaihi Wasalaam) said to me: ” Do not lie about me (or falsely attribute anything to me) for whoever lies about me will enter Hell” .
al-Bukhaari and Abu Dawood reported that ‘Abdullaah ibn az-Zubayr narrated from his father, az-Zubayr ibn al-‘Awwaam: “I heard the Messenger of Allah (Salallaahu Alaihi Wasalaam) say: ” Whoever lies about me deliberately, let him take his place in Hell” .
One of the major sins, al-Kabaa’ir, is pride. Abu Hurayrah (Radiallaahu Anhu) narrated: “The Messenger of Allah (Salallaahu Alaihi Wasalaam) said that Allah (Subhaanahu Wa Ta’ala) said, ” Pride is My cloak and greatness is My robe. Whoever competes with Me in respect of either of them, I shall admit him to Hellfire”. (according to another report, “I will make him taste Hellfire”) – Muslim.
Ibn Mas’ud said: “The Messenger of Allah (Salallaahu Alaihi Wasalaam) said, ” No one who has an atom’s weight of pride in his heart will enter Paradise” . A man said, “But what if a man likes his clothes and shoes to look good?” He said, “Allah is beautiful and loves beauty. Pride is rejecting the truth and looking down on people “. (Muslim).
3⃣ Killing a person for no legitimate reason
Allah says: ” If a man kills a believer intentionally, his recompense is Hell to abide therein [forever] and the Wrath and the Curse of Allah are upon him, and a dreadful Penalty is prepared for him “. (4:93)
al-Bukhaari narrates from Ibn ‘Umar that the Messenger of Allah (Salallaahu Alaihi Wasalaam) said: ” The believer has a chance so long as he does not spill blood that it is forbidden to spill ” . Ibn Umar (Radiallaahu Anhu) said, ” One of the situations from which there is no escape for the one who falls into it is the shedding of blood for no legitimate reason “. (Sahih al-Bukhaari, Fath ul-Baari, 12/187)
The Prophet (Salallaahu Alaihi Wasalaam) warned the Muslims against fighting one another and stated that the killer and his victim will both be in Hell. Abu Bakrah said: ” The Messenger of Allah (Salallaahu Alaihi Wasalaam) said, “If two Muslims face one another with swords, both the slayer and the slain will be in Hell”. I asked, or it was asked, “O Messenger of Allah (it is clear about) the slayer, but what about the slain?” He said, “He was trying hard to kill his counterpart “. (Muslim,4/2213)
