فضــــل الولاء لرسول اللٰہ صلی اللٰه علیہ وسلم
Whoever loves the Holy Prophet Muhammad (peace be upon him) will be with him in Paradise on the Day of Judgment.
[عن أنس بن مالك: أن أعرابيا، قال لرسول الله صلى الله عليه وسلم: متى الساعة؟ قال له رسول الله صلى الله عليه وسلم: ما أعددت لها؟ قال: حب الله ورسوله، قال: أنت مع من أحببت]
Sayyiduna Anas bin Malik رضي الله عنه says that a man came to the presence of the Messenger of Allah صلی اللہ علیہ وسلم and asked, "O Messenger of Allah صلی اللہ علیہ وسلم! When will the Day of Judgment come?" The Prophet صلی اللہ علیہ وسلم asked him, "What preparation have you made for the Day of Judgment?" The man replied, "Love of Allah and His Messenger!" The Prophet صلی اللہ علیہ وسلم said, "You will surely be with those whom you love." Sayyiduna Anas رضي الله عنه says: After embracing Islam, we never felt as much happiness as we did from this statement.

[عن عبد الله، قال: جاء رجل إلى رسول الله صلى الله عليه وسلم، فقال: يا رسول الله، كيف ترى في رجل أحب قوما ولما يلحق بهم؟ قال رسول الله صلى الله عليه وسلم: المرء مع من أحب]
Sayyiduna Abdullah bin Mas'ud رضي الله عنه says that a man came to the presence of the Messenger of Allah صلی اللہ علیہ وسلم and asked, "O Messenger of Allah صلی اللہ علیہ وسلم! What do you say about a person who loves such (righteous) people whose righteous deeds he has not reached?" The Prophet صلی اللہ علیہ وسلم said, "(On the Day of Judgment) a person will be with those whom he loves."

One who loves the Messenger of Allah ﷺ will be granted high ranks in Paradise.
[عن عائشة، قالت: جاء رجل إلى النبي صلى الله عليه وسلم فقال: يا رسول الله، والله إنك لأحب إلي من نفسي، وإنك لأحب إلي من أهلي، وأحب إلي من ولدي، وإني لأكون في البيت، فأذكرك فما أصبر حتى آتيك، فأنظر إليك، وإذا ذكرت موتي وموتك عرفت أنك إذا دخلت الجنة رفعت مع النبيين، وإني إذا دخلت الجنة خشيت أن لا أراك. فلم يرد عليه النبي صلى الله عليه وسلم حتى نزل جبريل بهذه الآية: {وَمَنْ يُطِعِ اللَّهَ وَالرَّسُولَ فَأُولَئِكَ مَعَ الَّذِينَ أَنْعَمَ اللَّهُ عَلَيْهِمْ مِنَ النَّبِيِّينَ وَالصِّدِّيقِينَ}]
Sayyida Aisha (may Allah be pleased with her) says that a man came to the Prophet Muhammad (peace be upon him) and said: O Messenger of Allah (peace be upon him)! I love you more than my own life and more than my son. When I am at home and remember you, I cannot be patient until I come to see you in person. But when I remember my death and your death, I realize that after entering Paradise, you will be in a high position among the Prophets, and even if I enter Paradise, I fear that due to my lower rank, I will not be able to see you (peace be upon him). The Prophet Muhammad (peace be upon him) did not respond to his companion until Angel Jibra'il (Gabriel) came with the following verse ﴿وَمَنْ یُّطِعِ اللّٰہَ…﴾: "And whoever obeys Allah and His Messenger - those will be with the ones upon whom Allah has bestowed favor of the Prophets, the truthful, the martyrs, and the righteous."

A believer attains the true sweetness of faith only through love for the Messenger of Allah ﷺ.
[عن أنس رضي الله عنه، عن النبي صلى الله عليه وسلم، قال: ثلاث من كن فيه وجد حلاوة الإيمان، أن يكون الله ورسوله أحب إليه مما سواهما ، وأن يحب المرء لا يحبه إلا لله، وأن يكره أن يعود في الكفر كما يكره أن يقذف في النار]
It is narrated from Sayyiduna Anas رضي الله عنه that the Prophet ﷺ said: There are three qualities; whoever possesses them has tasted the sweetness of faith. First, that Allah and His Messenger become the most beloved to him above all else. Second, that he loves a person solely for the sake of Allah's pleasure. Third, that he hates to return to disbelief as much as he hates to be thrown into the fire.
