Will he be seen? Don't shy away.
Abu Basir said that he told Imam Sadiq (a.s): “I have been told that God will not take away anyone’s eyesight unless He grants him a reward in Heaven.” Imam Sadiq (a.s) said: “There is some thing there (in Heaven) that is even better.” Abu Basir asked: “What is it?” The Imam (a.s) replied:
“It is seeing God’s face.”(Shia book, MISHKAT UL-ANWAR FI GHURAR AL-AKHBAR page 24, by Hassan ibn Fazl ibn Hassan Tabarsi)
We read in Shia book al-Mahasin” (p 60), and in “Musnad ar-Rida” (1/95):
101- عنه عن بكر بن صالح عن أبي الحسنالرضا (ع) قال من سره أن ينظر إلى الله بغير حجاب و ينظر الله إليه بغير حجاب فليتولآل محمد و ليتبرأ من عدوهم و ليأتم بإمام المؤمنين منهم فإنه إذا كان يوم القيامة نظر الله إليه بغير حجاب و نظر إلى الله بغير حجاب .
From Abul Hasan al-Rida (alaihi salam): Who wants to look at Allah without obstacle and Allah looks at him without obstacle, let him to befriend with family of Muhammad and be (far) away from their enemies, and follow Imam of believers from amongst them, (and if he would do that) in the doomsday Allah would look at him without obstacle and
he would look at Allah without obstacle.
shia books “Sahifa sajadiya al-kamila”. That’s a book of prays that attributed to imam Ali ibn Hussain ibn Ali ibn Abu Talib[4th Shia Imam) (may Allah be pleased with all of them).
In the chapter “The Whispered Prayer of the Lovers ” we can read (On-line)
My God, place us with him whom Thou hast chosen for Thy nearness and Thy friendship, purified through Thy affection and Thy love, given yearning for the meeting with Thee, made pleased with Thy decree, granted
GAZING UPON THY FACE, shown the favour of Thy good pleasure, given refuge from separation from Thee and Thy loathing.
Shia book, Sahifa Sajjadiya, In chapter “The Whispered Prayer of those asking for Mediation” you can read:
My God, I have no mediation with Thee but the tender acts of Thy clemency, nor any way to come to Thee but the gentle favours of Thy mercy and the intercession of Thy Prophet, the prophet of mercy, who rescued the community from confusion. Make these two my tie to attaining Thy forgiveness and let them take me to triumph through Thy good pleasure! My hope has dismounted in the sacred precinct of Thy generosity, my craving has alighted in the courtyard of Thy munificence. So actualize my expectation from Thee, seal my works with good, and place me among Thy selected friends, those whom Thou hast set down in the midst of Thy Garden, and settled in the abode of Thy honour,
whose eyes Thou hast gladdened by gazing upon Thee on the day of meeting Thee, and whom Thou hast made heirs to the sure stations in Thy neighbourhood!
Sahifa Sajjadiya, in chapter “The Whispered Prayer of the Abstainers” you can read:
لهِي فَزَهِّدْنا فِيها، وَسَلِّمْنا مِنْها بِتَوْفِيقِكَ وَعِصْمَتِكَ، وَانْزَعْ عَنَّا جَلابِيبَ مُخالَفَتِكَ، وَتَوَلَّ أُمُورَنا بِحُسْنِ كِفايَتِكَ، وَأَوْفِرْ مَزِيدَنا مِنْ سَعَةِ رَحْمَتِكَ، وَأَجْمِلْ صِلاتِنا مِنْ فَيْضِ مَواهِبِكَ، وَاغْرِسْ فِي أَفْئِدَتِنا أَشْجارَ مَحَبَّتِكَ، وَأَتْمِمْ لَنا أَنْوارَ مَعْرِفَتِكَ، وَأَذِقْنا حَلاوَةَ عَفْوِكَ، وَلَذَّةَ مَغْفِرَتِكَ، وَأَقْرِرْ أَعْيُنَنا يَوْمَ لِقآئِكَ بِرُؤْيَتِكَ، وَأَخْرِجْ حُبَّ الدُّنْيا مِنْ قُلُوبِنا كَما فَعَلْتَ بِالصَّالِحِينَ مِنْ صَفْوَتِكَ، وَالأَبْرارِ مِنْ خاصَّتِكَ بِرَحْمَتِكَ يا أَرْحَمَ الرَّاحِمِينَ، وَيا أَكْرَمَ الأَكْرَمِينَ.
My God, induce us to renounce it and keep us safe from it by Thy giving success and Thy preservation from sin. Strip from us the robes of opposing Thee, attend to our affairs through Thy good sufficiency, amplify our increase from the boundless plenty of Thy mercy, be liberal in our gifts from the overflow of Thy grants, plant in our hearts the trees of Thy love, complete for us the lights of Thy knowledge, give us to taste the sweetness of Thy pardon and the pleasure of Thy forgiveness,
gladden our eyes on the day of meeting Thee with the vision of Thee, dislodge the love of this world from our spirits, just as Thou hast done for the righteous, Thy selected friends, and for the pious, those whom Thou hast singled out! O Most Merciful of the merciful, O Most Generous of the most generous!
In fact, Ali Zayn al-`Abidin constantly mentions looking at God in his Sahifah, examples:”
وَشَوَّقْتَهُ إِلىٰ لِقَائِكَ وَرَضَّيْتَهُ بِقَضائِكَ، وَمَنَحْتَهُ بِالنَّظَرِ إلىٰ وَجْهِكَ
“Made him yearn for the meeting with You, made him pleased with Your decree and
granted him (the joy of) gazing upon Your face”
وَلا تَحْجُبْ مُشْتاقِيكَ عَنِ النَّظَرِ إلَىٰ جَمِيلِ رُؤْيَتِكَ
“Place no veil to obstruct those who yearn from
seeing the beauty upon looking at you”
وَشَوْقِي إلَيْكَ لا يَبُلُّهُ إِلاَّ النَّظَرُ إِلىٰ وَجْهِكَ
“My yearning for you shall not be quenched except after
looking at your face”
فِي الْقُرْبىٰ مِنْكَ، وَالزُّلْفىٰ لَدَيْكَ، وَالتَّمَتُّعِ بِالنَّظَرِ إلَيْكَ،
“Through nearness to you, proximity with you and the enjoyment of
gazing upon You”
