Abu Huraira reported God’s messenger as Saying, “He who holds fast to my sunna when my people are in a corrupt state will have the reward of a hundred martyrs.” ^{1 1} The source is lacking. The editor of Damascus edition quotes Mirak Shah and others as saying Bayhaqi gives the tradition in his kitab az-Zuhd as coming from Ibn Abbas.

Bismillāh wallāhu Akbar [Allāhumma minka wa lak] Allāhumma taqabbal minnī. With the Name of Allah, Allah is the Most Great! [O Allah, from You and to You.] O Allah, accept it from me. Reference: Muslim 3/ 1557, Al-Bayhaqi 9/287.

It was reported that the Messenger of Allah ﷺ said, “Whoever reads Sūrat al-Kahf on the night of Jumu’ah, a light will shine for him which extends from him to the Ancient House (i.e., the Kaʿbah).” Reference: Sunan al-Darimi 3312; Sunan Al-Bayhaqi 5856; Sahīh al-Targhīb wa at-Tarhīb 736. Note: Jumu’ah is not equivalent to Friday, rather it begins at Maghrib/sunset of Thursday and ends as the maghrib/sunset time comes in on Friday.

Allāhumma lā tu'ākhidhnī bimā yaqūlūn, waghfir lī mā lā ya`lamūn [waj`alnī khayran mimmā yaẓunnūn]. O Allah, do not call me to account for what they say and forgive me for what they have no knowledge of [and make me better than they imagine]. Reference: Al-Bukhari, Al-'Adabul-Mufrad no. 761. See Al-Albani, Sahih Al-'Adabul-Mufrad (no. 585). The portion between brackets if from Al-Bayhaqi, Shu'ab Al-Iman 4/228, and comes another account.

Allāhumma rabba hādhihi 'd-da'wati 't-tāmmah waṣ-ṣalāti 'l-qā'imah, 'āti Muhammadani 'l-wasīlata walfaḍīlata, wab 'ath-hu maqāma 'm-mahmūdani 'l-ladhī wa`adtahu, ['innaka lā tukhliful-mī'ād] O Allah , Lord of this perfect call and established prayer. Grant Muhammad the intercession and favor, and raise him to the honored station You have promised him, [verily You do not neglect promises]. Reference: Al-Bukhari 1/152, and the addition between brackets is from Al-Bayhaqi 1/410 with a good (Hasan) chain of narration. See 'Abdul-Azlz bin Baz's Tuhfatul-'Akhyar, pg. 38.

Allāhumma iyyāka na`bud, wa laka nuṣallī wa nasjud, wa ilayka nas`ā wa naḥfid, narjū raḥmatak, wa nakhshā `adhābak, inna `adhābaka bilkāfirīna mulḥaq. Allāhumma innā nasta`īnuk, wa nastaghfiruk, wa nuthnī `alaykal-khayr, wa lā nakfuruk, wa nu'minu bik, wa nakhḍa`u lak, wa nakhla`u man yakfuruk. O Allah, You alone do we worship, and to You we pray and bow down prostrate. To You we hasten to worship and to serve. Our hope is for Your mercy, and we fear Your punishment. Surely, Your punishment of the disbelievers is at hand. O Allah, we seek Your help and Your forgiveness, and we praise You beneficently. We do not deny You and we believe in You. We surrender to You and renounce whoever disbelieves in You. Reference: Al-Bayhaqi graded its chain authentic in As-Sunan Al-Kubra. Al-Albani said in 'Irwa'ul-GhaliL 2/170 that its chain is authentic as a statement of 'Umar.

Allāhumma’hdinī fī man hadayt, wa `āfinī fī man `āfayt, wa tawallanī fī man tawallayt, wa bārik lī fī mā a`atayt, wa qinī sharra mā qaḍayt, fa innaka taqḍī wa lā yuqḍā `alayk, innahu lā yadhillu man wālayt, [wa lā ya`izzu man `ādayt] , tabārakta Rabbanā wa ta`ālayt. O Allah, guide me with those whom You have guided, and strengthen me with those whom You have given strength. Take me to Your care with those whom You have taken to Your care. Bless me in what You have given me. Protect me from the evil You have ordained. Surely, You command and are not commanded, and none whom You have committed to Your care shall be humiliated [and none whom You have taken as an enemy shall taste glory]. You are Blessed, Our Lord, and Exalted. Reference: Abu Dawud, Ibn Majah, An-Nasa'i, At-Tirmidhi, Ahmad, Ad-Darimi, Al-Hakim, and Al-Bayhaqi. See also Al-Albani, Sahih At-Tirmidhi 1/144, Sahih Ibn Majah 1/194, and 'Irwa'ul-GhaW. 2/ 172.

“Yazīd bin Ziyād narrated to me, from Muḥammad bin Ka‘b Al-Quraẓiyy who said: ‘When they gathered together (at his house to lay siege to it and murder him), and amongst them was Abū Jahl bin Hishām, he said when they were at his door: ‘Muḥammad claims that if you follow him regarding his matter that you will be the kings of the Arabs and the non-Arabs, and then you all will be resurrected after your deaths and you will be granted gardens like the gardens of Jordan. And if you don’t, amongst you will be those who are slaughtered (referring to those who insisted on attacking Islam and the Muslims), and then you all will be resurrected after your deaths, and a fire will be placed for you in which you will be burnt.’ He (the narrator) said: ‘And the Messenger came out to them and took a handful of dirt and then said, ‘I do say that, and you are one of them (those who would be killed and enter the fire).’ Allah veiled their sight so they were unable to see him, and he began to sprinkle that dirt on their heads while reciting the verses from Yāsīn: “(1) Yā Sīn (2) By the wise Quran, (3) you [Muḥammad] are truly one of the messengers sent (4) on a straight path” until (he reached) “blocking their vision: they cannot see.” By the time he finished reciting those verses there was no one except that he had put dirt on his head. Then he left in the direction he wanted to go…” Reference: Ibn Mundhir and Ibn Abi Hatim in Ad-Durr 5/258; al-Bayhaqi in Ad-Dala'il 2/470.
